RESUMO

A new injectable solution containing low-molecular-weight hyaluronic acid (HA) and a specific amino acid mixture was formulated with proper aesthetic performance for the main signs of facial skin photoaging. The present study aimed to investigate its new application for rejuvenating and augmenting labia majora using clinical and biometric assessments. Three sessions of intradermal injections were performed using 3 ml of test extracellular matrix (ECM) for 10 eligible post-menopause female subjects (age 53.6 ± 7.93 years). The effectiveness of the intervention was assessed by an independent physician using before-and-after pictures based on the physician's global assessment score. Objective biophysical skin assessments, including skin hydration, skin erythema, and melanin index, as well as elasticity parameters including firmness (R0), gross elasticity (R2), and net elasticity (R5), were also performed before the first injection and then on the 2nd and 12th weeks after the last session. Patients' satisfaction and all reported or observed adverse events were documented. At week 12, all the subjects reported an aesthetic improvement of 25% or more in rejuvenation and sagging of the labia major area. A statistically significant improvement was also detected in R0 and R5 at week 12 (p-values 0.005 and 0.022, respectively). Patient satisfaction surveys revealed a median score of 8 at both follow-up visits. The results showed a new indication of the tested HA ECM for providing a beneficial, durable, rejuvenating effect on the labia majora with a good safety profile.

RESUMO

INTRODUCTION: Clinical Practice Guidelines (CPGs) development and implementation in the Kingdom of Saudi Arabia are suboptimal. The Kingdom's Vision 2030 envisages a transformational change to achieve an effective, integrated, value-based ecosystem focused on patient health. OBJECTIVES: This study aimed to develop a CPG appraisal tool that will support the realization of the Kingdom's Vision 2030 through the development of high-quality and highly implementable CPGs. To maximize its impact, all vital healthcare paradigms, such as systems thinking, value-based healthcare, and information technology, will robustly be incorporated in the tool. METHODS: The Saudi Health Council through its National Center of Evidence-Based Medicine (NCEBM) embarked on a program to develop this appraisal tool. A taskforce of experts was selected based on their experience in evidence-based practice and training. The task force, through a methodology of extensive literature review, deliberation, outside experts' feedback, and Delphi and consensus voting, developed a prototype appraisal tool that was named the Holistic Appraisal Tool for CPGs (HAT-CPG). RESULTS: The HAT-CPG was developed comprising three sections: an initial basic information section, an internal validity section, and an external validity section with a total of 13 section items and 73 reporting elements. CONCLUSION: It is envisaged that the Holistic Appraisal Tool will support CPG developers and users in Saudi Arabia in realizing the objectives for which it was developed.

RESUMO

It has been suggested that maladaptive perfectionists are more prone to concern over their performance outcomes than adaptive perfectionists. Performance outcome evaluation is reflected in the amplitude of feedback-related negativity (FRN) in brain electroencephalography (EEG). Hence, the amplitude of the FRN after receiving unfavorable feedback indicating a negative performance outcome may reflect personality characteristics. In other words, EEG could be a better marker of personality characteristics than self-report measures. However, the FRN component has not yet been investigated between different types of perfectionists. In the present study, group differences in the FRN were examined between two groups of adaptive and maladaptive perfectionists and a group of non-perfectionists during a monetary gambling task. We observed a larger FRN amplitude for adaptive perfectionists than for maladaptive perfectionists. This finding is consistent with previous reports that reward prediction error is reflected in the amplitude of the FRN. This difference in FRN could be interpreted as the pessimistic outcome expectation biases in maladaptive perfectionists.

RESUMO

Saudi Arabia's ambitious Vision 2030 project was launched in 2016 as a strategy for economic development and national growth, with 11 Vision Realization Programs put in charge of its implementation. The backbone of its Transformation Program for the Health Sector has been the definition of a new Model of Care aiming to deliver 42 coordinated interventions across 6 Systems of Care, with the development of clinical guidelines identified as a key cross-cutting intervention to foster the use of national, evidence-based practices across KSA, reduce care variation, and promote accountable care. This article provides an overview of the history, progress to date, and future outlook of the recently initiated National Guidelines Center in Saudi Arabia, established in collaboration between the Health Holding Company and the Saudi Health Council represented by its National Center for Evidence-based Medicine. The lessons learnt from previous guideline initiatives are grouped under the Center's design principles of high quality, relevance, practical implementation, and sustainability. Aspects setting the project apart from previous endeavors have been its focus on extensive engagement with key stakeholders in the Saudi guideline ecosystem, the co-development of evidence-based recommendations with aligned key performance measures, and the implementation of guideline recommendations in the clinical workflow via integrated electronic order sets. Nine activity streams aim to enable the Center to take its place among the leading regional and global guideline developing organizations and to optimally support clinicians and patients, Saudi Arabia's health sector transformation, and the work of guideline communities worldwide.

RESUMO

Rainfall estimation using remote sensing products is an alternative to in situ measurement rainfall due to their high temporal and spatial resolution. Using satellite soil moisture (SM) observations in the SM to Rain (SM2RAIN) algorithm have a great potential to estimate rainfall. SMA2RAIN-NWF algorithm is a reinforced version of a SMA2RAIN algorithm which was developed to estimate rainfall through the integration of the SM2RAIN algorithm and the net water flux (NWF) model. A new release of SMA2RAIN-NWF algorithm uses the Advanced Microwave Scanning Radiometer 2 (AMSR2) SM dataset as input datasets. The aim here is to assess the SMA2RAIN-NWF by using multiple SM products including ASCAT, and their integration in four aggregations (AGGR) periods (1, 7, 14, and 30 days) by comparing with rainfall observation of 15 stations over the Lake Urmia basin, Iran for the period January 2015 to December 2019. The Discrete Cosine Transform (DCT) method is applied to fill the gap in the satellite SM time series. Moreover, the effect of land cover classes (grasslands, croplands, and urban) on rainfall estimation is investigated. Considering the Kling-Gupta efficiency (KGE) and correlation coefficient (R) values in comparisons of calibration and validation revealed that urban areas experienced a minimum decrement rate (2-5 %). A comparison of three SM products (ASCAT, ASCAT+SMAP, and ASCAT+DCT) show that all products had a high performance on a daily time scale in term of the KGE and R. The results showed that algorithm performance gradually rose via an increase in AGGR levels, reaching KGE and R values of 0.8 and above. Furthermore, the comparison of SM2RAIN-NWF and SM2RAIN show an improvement of SM2RAIN-NWF performance across various AGGRs.

RESUMO

Alzheimer's disease (AD) is a kind of neuropsychiatric illness that affects the central nervous system. In this disease, the accumulation of amyloid-beta increases, and phosphorylated tau (P-tau) protein is one of the ways to treat this disease is to reduce the accumulation of amyloid-beta. Various studies have demonstrated that pharmacological approaches have considerable effects in the treatment of AD, despite the side effects and challenges. Cholinesterase inhibitors and the NMDA receptor antagonist memantine are presently authorized therapies for AD. Memantine and Donepezil are the most common drugs for the prevention and therapy of AD with mechanisms such as lessened ß-amyloid plaque, affecting N-Methyl-D-aspartate (NMDA) receptors. Diminution glutamate and elevated acetylcholine are some of the influences of medications administrated to treat AD, and drugs can also play a role in slowing the progression of cognitive and memory impairment. A new pharmacological approach and strategy are required to control the future of AD. This review appraises the effects of memantine, donepezil, rivastigmine, and aducanumab in clinical trials, in vitro and animal model studies that have explored how these drugs versus AD development and also discuss possible mechanisms of influence on the brain. Research in clinical trials has substantial findings that support the role of these medications in AD treatment and ameliorate the safety and efficacy of AD therapy, although more clinical trials are required to prove their effectiveness.

RESUMO

OBJECTIVE: Mildly symptomatic COVID-19 patients may seek medical attention either in the Emergency Department (ED) or Ambulatory Clinics (AC). However, it is unclear if ED patients have different characteristics and outcomes than AC patients when discharged under telemedicine surveillance, which we explored in this study. METHODS: Patients with mild or asymptomatic COVID-19 disease referred to a multidisciplinary Telemedicine clinical service (TM-CS) program in an urban tertiary-care hospital, between June 2020 and February 2021, were evaluated. Those referred from ED were labeled "ED Group" and ones from AC as "AC Group." Their characteristics, clinical features and outcomes including telemedicine parameters, subsequent ED visits, hospital admission, oxygen requirements, intensive care unit (ICU) admission, and mortality were compared. RESULTS: Out of 1132 confirmed non-admitted COVID-19 patients, 526 with mild (89%) or asymptomatic (11%) disease were enrolled in TM-CS. Majority of these were referred from ED (n = 370; 70%) and rest (n = 156, 30%) from the AC. Patients in the ED group compared to AC group, had higher BMI (28.9 vs. 27.5), higher Charlson Comorbidity Index (1.4 vs. 0.9), and higher incidence of comorbidities (50% vs. 22%), P ≤ 0.01. However, there were no differences in the ED and AC groups in subsequent ED visits (26% vs. 24%), hospital admission (18% vs. 15%), oxygen requirements (5% vs. 4%), ICU admission (1% vs. 2%), and mortality (0.3% vs. 0.6%), respectively (P > 0.40). CONCLUSION: Significant number of mild COVID-19 patients head to the ED for initial assistance but have similar outcomes to AC patients. TM-CS could be a safe alternative for follow-up monitoring of these patients.

RESUMO

Type 2 diabetes (T2D), which affects many people around the world, is one of the diseases that is on the rise. Various studies have revealed that insulin resistance and lessened insulin production have been associated with T2D, and they also show that this disease can have a genetic origin and is associated with different genes, such as KCNQ1, PPAR-γ, calpain-10, ADIPOR2, TCF7L2, which can be utilized as therapeutic targets. Different therapeutic approaches and strategies such as exercise and diet, pharmacological approaches, and utilization of nanoparticles in drug delivery and gene therapy can be effective in the treatment and control of T2D. Glucagon-like peptide 1 (GLP-1) and sodiumglucose cotransporter-2 (SGLT2) have both been considered as drug classes in the treatment of T2D and T2D-related diseases such as cardiovascular disease and renal disease, and have considerable influences such as diminished cardiovascular mortality in individuals with T2D, ameliorated postprandial glycaemia, ameliorated fasting glycaemia, and diminished bodyweight on disease treatment and improvement process. In the present review article, we have attempted to explore the risk factors, genes, and diseases associated with T2D, therapeutic approaches in T2D, the influences of drugs such as dapagliflozin, metformin, acarbose, Januvia (sitagliptin), and ertugliflozin on T2D in clinical trials and animal model studies. Research in clinical trials has promising results that support the role of these drug approaches in T2D prophylaxis and ameliorate safety even though additional clinical research is still obligatory.

RESUMO

Open innovation is a young arena in research that is fascinating the attention of a growing number of scholars. However, there are not enough studies that investigate open innovation performance. The pharmaceutical industry with the most Research and Development (R&D) intensity has been targeted by this new paradigm. This study explores the effect of entrepreneurial orientation on open innovation performance, considering the mediating role of desorptive capacity, which is defined as the firm's capability to recognize outward technology transfer opportunities and to facilitate it. We use structural equation modeling to examine the hypotheses on a dataset from 100 Iranian pharmaceutical manufacturers in 2018. The results of the study support our conceptual model. Our findings indicate that a firm's entrepreneurial orientation and desorptive capacity have a positive effect on its open innovation performance. Moreover, desorptive capacity has a mediating effect in the relation of entrepreneurial orientation and open innovation performance. This denotes that our new model contributes to the concept of desorptive capacity in the context of open innovation.

RESUMO

BACKGROUND: In patients with hepatic cystic echinococcosis (CE), treatment effectiveness, outcomes, complications, and recurrence rate are controversial. Endocystectomy is a conservative surgical approach that adequately removes cyst contents without loss of parenchyma. This conservative procedure has been modified in several ways to prevent complications and to improve surgical outcomes. This systematic review aimed to evaluate the intraoperative and postoperative complications of endocysectomy for hepatic CE as well as the hepatic CE recurrence rate following endocystectomy. METHODS: A systematic search was made for all studies reporting endocystectomy to manage hepatic CE in PubMed, Web of Science, and Cochrane CENTRAL databases. Study quality was assessed using the methodological index for non-randomized studies (MINORS) criteria and the Cochrane revised tool to assess risk of bias in randomized trials (RoB2). The random-effects model was used for meta-analysis and the arscine-transformed proportions were used to determine complication-, mortality-, and recurrence rates. This study is registered with PROSPERO (number CRD42020181732). RESULTS: Of 3,930 retrieved articles, 54 studies reporting on 4,058 patients were included. Among studies reporting preoperative anthelmintic treatment (31 studies), albendazole was administered in all of them. Complications were reported in 19.4% (95% CI: 15.9-23.2; I2 = 84%; p-value <0.001) of the patients; biliary leakage (10.1%; 95% CI: 7.5-13.1; I2 = 81%; p-value <0.001) and wound infection (6.6%; 95% CI: 4.6-9; I2 = 27%; p-value = 0.17) were the most common complications. The post-endocystectomy mortality rate was 1.2% (95% CI: 0.8-1.8; I2 = 21%; p-value = 0.15) and the recurrence rate was 4.8% (95% CI: 3.1-6.8; I2 = 87%; p-value <0.001). Thirty-nine studies (88.7%) had a mean follow-up of more than one year after endocystectomy, and only 14 studies (31.8%) had a follow-up of more than five years. CONCLUSION: Endocystectomy is a conservative and feasible surgical approach. Despite previous disencouraging experiences, our results suggest that endocystectomy is associated with low mortality and recurrence.

RESUMO

Mesenchymal Stem Cells (MSCs), a form of adult stem cells, are known to have a selfrenewing property and the potential to specialize into a multitude of cells and tissues such as adipocytes, cartilage cells, and fibroblasts. MSCs can migrate and home to the desired target zone where inflammation is present. The unique characteristics of MSCs in repairing, differentiation, regeneration, and the high capacity of immune modulation have attracted tremendous attention for exerting them in clinical purposes, as they contribute to the tissue regeneration process and anti-tumor activity. The MSCs-based treatment has demonstrated remarkable applicability towards various diseases such as heart and bone malignancies, and cancer cells. Importantly, genetically engineered MSCs, as a stateof- the-art therapeutic approach, could address some clinical hurdles by systemic secretion of cytokines and other agents with a short half-life and high toxicity. Therefore, understanding the biological aspects and the characteristics of MSCs is an imperative issue of concern. Herein, we provide an overview of the therapeutic application and the biological features of MSCs against different inflammatory diseases and cancer cells. We further shed light on MSCs' physiological interaction, such as migration, homing, and tissue repairing mechanisms in different healthy and inflamed tissues.

RESUMO

Chronic stress and high levels of glucocorticoids produce functional and structural changes in brain and especially in the hippocampus, an important limbic system structure that plays a key role in cognitive functions including learning and memory. Alzheimer's disease (AD) is a chronic neurodegenerative disease that usually starts slowly and worsens over time. Indeed, cognitive dysfunction, neuronal atrophy, and synaptic loss are associated with both AD and chronic stress. Recent preclinical and clinical studies have highlighted a possible link between chronic stress, cognitive decline and the development of AD. It is suggested that Tau protein is an essential mediator of the neurodegenerative effects of stress and glucocorticoids towards the development of AD pathology. Recent findings from animal and humans studies demonstrated that saffron and its main constitutive crocin are effective against chronic stress-induced cognitive dysfunction and oxidative stress and slowed cognitive decline in AD. The inhibitory actions on acetylcholinesterase activity, aggregation of beta-amyloid protein into amyloid plaques and tau protein into neurofibrillary tangles, and also the antioxidant, anti-inflammatory, and the promotion of synaptic plasticity effects are among the possible mechanisms to explain the neuroprotective effects of saffron. New evidences demonstrate that saffron and its main component crocin might be a promising target for cognition improvement in AD and stress-related disorders.

RESUMO

Hypothyroidism is one of the most common chronic endocrine conditions. However, as symptoms of hypothyroidism are non-specific, up to 60% of those with thyroid dysfunction are unaware of their condition. Left untreated, hypothyroidism may contribute to other chronic health conditions. In the Arabian Gulf States, hypothyroidism is thought to be common, but is underdiagnosed, and management approaches vary. An advisory board of leading Saudi endocrinologists and policy advisers was convened to discuss and formulate recommendations for the diagnosis and management of hypothyroidism in Saudi Arabia based on their clinical expertise. The final document was shared with leading endocrinologists from the other Gulf  Cooperation Council (GCC) and aconsensus report was generated and summerized in this article. While there is no consensus regarding population screening of hypothyroidism, current recommendations suggest screening patients with risk factors, including those with a history of head or neck irradiation, a family history of thyroid disease or pharmacological treatment that may affect thyroid function. Evidence from a cross-sectional study in Saudi Arabia suggests screening the elderly (> 60 years), at least in the primary care setting. In Saudi Arabia, the incidence of congenital hypothyroidism is approximately 1 in every 3450 newborns. Saudi nationwide population prevalence data are lacking, but a single-centre study estimated that the prevalence of subclinical hypothyroidism in the primary care setting was 10%. Prevalence rates were higher in other cross-sectional studies exclusively in women (13-35%). The recommendations included in this  article aim to streamline the diagnosis and clinical management of hypothyroidism in the GCC, especially in the primary care setting, with the intention of improving treatment outcomes. Further study on the incidence, prevalence and risk factors for, and clinical features of, hypothyroidism in the GCC countries is required.

RESUMO

Background A wide range of reports on the incidence of diabetic ketoacidosis (DKA) at the onset of type 1 diabetes mellitus (T1DM) in children have been published worldwide. Reports from Saudi Arabia are limited. The aim of this study was to assess the incidence, clinical pattern and severity of DKA in children with newly diagnosed T1DM and the association of autoimmune conditions with initial DKA occurrence at King Abdulaziz Medical City - Jeddah. Methods This retrospective chart review was conducted during the period 2005-2015. All newly diagnosed T1DM children during the study period were investigated (n = 390). Data were collected on the demographic characteristics, body mass index (BMI), DKA severity, length of hospital stay and follow-up data on the type of diabetes therapy. Results The incidence of DKA among newly diagnosed T1DM pediatric patients was 37.7% (n = 147). Moderate and severe DKA cases were significantly higher among female children (p = 0.04). Patients diagnosed with DKA had lower BMI (20.87 ± 5.21) than their counterparts (p = 0.03). The median length of hospital stay was higher among severe DKA compared to moderate and mild cases (5.0, 4.5 and 4.0 days, respectively). Conclusions The incidence of DKA among newly diagnosed T1DM is still high compared to developed countries; however, it is relatively lower than previous reports in Saudi Arabia. Immediate interventions, such as awareness campaigns, are vital to reduce the burden of this preventable health sequela among children with DM.

RESUMO

BACKGROUND/OBJECTIVE: Biliary leakage is a potential complication of liver resection and is still a concern. The aim of the present study was to evaluate the effectiveness of four routinely used sealants in preventing bile leakage under pressure from an induced perforation of the gallbladder in a porcine model. METHODS: Forty Landrace pigs were randomly assigned to one of five groups. These included a control group (n = 8) and one group each for the sealants TachoSil®, TissuCol Duo®, Coseal®, and FloSeal® (n = 8 per group). In the control group, the perforation was left unsealed. To evaluate the biliostatic potential of the sealants, we measured the pressure that was needed to induce leakage (mmHg) and the gallbladder volume (cc) at the time of leakage in each group. RESULTS: A significantly higher mean pressure was required to induce leakage in the sealant groups compared with the control group. However, the biliostatic effects were heterogeneous among the sealant groups. Sealants with the highest to lowest effectiveness were TachoSil, Coseal, TissuCol, and FloSeal. The mean gallbladder volume at the time of leakage also varied between sealant groups. CONCLUSION: Biliostatic properties are markedly improved by the use of modern sealants compared with using no sealant. However, the advantages and disadvantages of using sealants should be carefully considered in each clinical situation. The effectiveness of the sealants should be evaluated in chronic and clinical studies.

RESUMO

The prevalence rates of ß-thalassemia (ß-thal) and Sickle Cell Disease (SCD) in Saudi Arabia are considered one of the highest compared to surrounding countries in the Middle East (0.05% and 4.50%, respectively). In this study, Secondary data analysis was obtained from the premarital screening and genetic counseling program (PMSGC), and included 12,30,582 individuals from February 2011 to December 2015. Prevalence rates (per 1000 population) for ß-thal and SCD were calculated for carrier status, disease status and their combination. During the 5-year study period, the overall prevalence rate per 1000 population for ß-thal was 13.6 (12.9 for the trait and 0.7 for the disease). The prevalence rate for SCD was 49.6 (45.8 for the trait and 3.8 for the disease). Rates for ß-thal were found to decrease from 24.2 in 2011, to 12 in 2015. However, SCD rates remained rather constant and ranged from 42.3 in 2011 to 49.8 in 2015. The highest rate for both ß-thal and SCD was observed in the Eastern and Southern regions. This result reflects major accomplishment of the PMSGC. This study recommends further improvement in preventive measures in high-risk regions, and enhanced community awareness to provide the highest rate reduction for these disorders.

RESUMO

OBJECTIVE: To evaluate the effect of PRP-enriched gelfoam on the healing of chronic TM perforation in comparison with gelfoam alone. METHODS: In this double-blind randomized clinical trial Patients with chronic tympanic membrane were randomly allocated to two groups; intervention group underwent tympanoplasty with platelet rich plasma (PRP)- enriched gel foams and control group underwent operation with conventional gel foams alone. Patients information was recorded 4 and 12 months after surgery. RESULTS: Eventually 24 patients (12 males and 12 females) with a mean age of 43.33 ± 12.34 years in intervention and 41.33 ± 10.02 years in control group underwent analysis (p = 0.667). Complete TM healing was seen in 8 (66.67%) patients in intervention group and 3 (25%) patients in control group three months after intervention (p = 0.031, OR = 5.98). CONCLUSION: Addition of PRP to conventional gelfoams used in TM perforation repair increases the complete healing rate of TM perforation with less morbidity and complications.

RESUMO

OBJECTIVE: No recent original studies on the pattern of diet are available for Saudi Arabia at the national level. The present study was performed to describe the consumption of foods and beverages by Saudi adults. DESIGN: The Saudi Health Interview Survey (SHIS) was conducted in 2013. Data were collected through interviews and anthropometric measurements were done. A diet history questionnaire was used to determine the amount of consumption for eighteen food or beverage items in a typical week. SETTING: The study was a household survey in all thirteen administrative regions of Saudi Arabia. SUBJECTS: Participants were 10 735 individuals aged 15 years or older. RESULTS: Mean daily consumption was 70·9 (se 1·3) g for fruits, 111·1 (se 2·0) g for vegetables, 11·6 (se 0·3) g for dark fish, 13·8 (se 0·3) g for other fish, 44·2 (se 0·7) g for red meat, 4·8 (se 0·2) g for processed meat, 10·9 (se 0·3) g for nuts, 219·4 (se 5·1) ml for milk and 115·5 (se 2·6) ml for sugar-sweetened beverages. Dietary guideline recommendations were met by only 5·2 % of individuals for fruits, 7·5 % for vegetables, 31·4 % for nuts and 44·7 % for fish. The consumption of processed foods and sugar-sweetened beverages was high in young adults. CONCLUSIONS: Only a small percentage of the Saudi population met the dietary recommendations. Programmes to improve dietary behaviours are urgently needed to reduce the current and future burden of disease. The promotion of healthy diets should target both the general population and specific high-risk groups. Regular assessments of dietary status are needed to monitor trends and inform interventions.

RESUMO

Objective The basal ganglia are a group of structures that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex and thalamus. Some speech disorders such as stuttering can resulted from disturbances in the circuits between the basal ganglia and the language motor area of the cerebral cortex. Stuttering consists of blocks, repetitive, prolongation or cessation of speech. We present a 7.5 -year-old male child with bilateral basal ganglia lesion in globus pallidus with unclear reason. The most obvious speech disorders in patient was stuttering, but also problems in swallowing, monotone voice, vocal tremor, hypersensitivity of gag reflex and laryngeal dystonia were seen. He has failed to respond to drug treatment, so he went on rehabilitation therapy when his problem progressed. In this survey, we investigate the possible causes of this type of childhood neurogenic stuttering.
