Saussurea costus (S. costus) belongs to family of Asteraceae and is one of the therapeutic plants extensively used as a traditional medicine in Saudi Arabia. Constituents of this plant have the potential to be developed as bioactive molecules. Among Arabs, the prevalence of thyroid disorders ranges from 6.18 % to 47.34% and hypothyroidism has been reported to be the most prevalent. Although there is no natural treatment that can directly replace thyroid hormones, their role as an alternate treatment or as an add-on to available thyroid treatment has been explored. Flavanoids and antioxidant properties of S. costus may be an important mechanism involved in supporting its medicinal use. Current data on the possible role of S. costus in thyroid disorders is lacking and the available evidence is inconclusive. This review deal with the current understanding of use and myth regarding the use of this medicinal plant in thyroid disease.

Background/aim In recent years, the diagnostic utility of urinary protein levels has been demonstrated for the early detection and progression of kidney disease. This study aimed to evaluate the associations of the non-albumin protein (NAP) with different urinary marker for tubular and glomerular damage in patients with type 2 diabetes (T2D). Methods In this observational cross-sectional study, 424 patients with T2D duration > 10 years were classified into two groups according to estimated glomerular filtration rate (eGFR). The ratios of different urinary markers (albumin, NAP, total protein, transferrin, retinol-binding protein (RBP), and neutrophil gelatinase-associated lipocalin (NGAL) to creatinine were analyzed. Results The levels of urinary biomarkers increased significantly with decrease in eGFR levels. In the group with moderately decreased eGFR, the albumin to-creatinine ratio (ACR), non-albumin protein-to-creatinine ratio (NAPCR), and total protein-to-creatinine ratio (PCR) were independently associated with all urinary markers after being adjusted for risk factors. The area under the receiver operating characteristics (ROC) curve for ACR and PCR had a better diagnostic value than other urinary biomarkers. Comparing ROC curve of NAPCR with other urinary biomarkers, it was significantly better than NGAL/Cr (p = 0.033). Conclusions The findings of the present study confirm that ACR and PCR are diagnostic biomarkers in T2D patients with decreased eGFR. NAPCR in these patients diagnostically only outperformed NGAL/Cr.

Metformin is a widely prescribed medication for the treatment of type 2 diabetes mellitus (T2DM). It possesses effective roles in various disorders, including cancer, dyslipidemia, and obesity. However, the underlying mechanisms of metformin's multiple benefits are not fully understood. Herein, a mass spectrometry-based untargeted metabolomics approach was used to investigate the metabolic changes associated with the administration of a single dose of metformin in the plasma of 26 healthy subjects at five-time points; pre-dose, before the maximum concentration of metformin (Cmax), Cmax, after Cmax, and 36 h post-dose. A total of 111 metabolites involved in various biochemical processes were perturbed, with branched-chain amino acid (BCAA) being the most significantly altered pathway. Additionally, the Pearson similarity test revealed that 63 metabolites showed a change in their levels dependent on metformin level. Out of these 63, the level of 36 metabolites was significantly altered by metformin. Significantly altered metformin-dependent metabolites, including hydroxymethyl uracil, propionic acid, glycerophospholipids, and eicosanoids, pointed to fundamental biochemical processes such as lipid network signaling, energy homeostasis, DNA lesion repair mechanisms, and gut microbiota functions that could be linked to the multiple beneficial roles of metformin. Thus, the distinctive metabolic pattern linked to metformin administration can be used as a metabolic signature to predict the potential effect and mechanism of actions of new chemical entities during drug development.

Background Primary Empty Sella (PES) syndrome is an increasingly common disorder, mostly diagnosed as an incidental finding during brain imaging scans. We intended to review the clinical management and hormonal profile of patients with PES. Methods The study included ten-year retrospective analysis of registry containing PES cases in the period 2007 to 2017, from a single tertiary care center. The keyword ‘primary empty sella’ was used to retrieve patient details from the radiology unit. The clinical and biochemical profile of PES patients was analyzed. Case management of PES patients and their rate of referral to endocrinologists was explored. Results The registry had 765 cases with a male: female ratio of 1:3.8 suggesting female predominance by almost four times. Although not significant, the onset of disease was earlier for males [Mean ± standard deviation (SD) (46.7 years ±17.3 vs 48.8 years±14.1), p = 0.110]. Almost 79% of the cases were found as an incidental finding during Magnetic Resonance Imaging. Of the total PES cases, only 20% were referred to the endocrinologists and the rest were handled by general physicians. Only 1–2.5% of the cases were evaluated for gonadal, growth and adrenal hormones by the general physicians. The hormonal evaluation by the endocrinologists was also found to be sub-optimal. Headache and visual disturbances were the most common presenting complaints followed by menstrual abnormalities. Endocrine abnormalities like thyroid dysfunction, hyperprolactinemia, hypogonadism and hypocortisolism were highly prevalent among those assessed. Conclusion There is a gross under-evaluation of hormonal assessment and minimal case-referral to Endocrinologists. PES is associated with varying degrees of hormonal dysfunction, and hence early assessment and management is needed. Establishing a standard protocol for diagnosis and case management is essential with the involvement of a multidisciplinary team consisting of endocrinologists, neurologists, primary care phys icians and ophthalmologists.

Background: High prevalence of undiagnosed cases of diabetes mellitus (DM) has increased over the last two decades, most patients with DM only become aware of their condition once they develop a complication. Limited data are available regarding the knowledge and awareness about DM and the associated risk factors, complications and management in Saudi society. Aim: This study aimed to assess knowledge of DM in general Saudi society and among Saudi healthcare workers. Results: Only 37.3% of the participants were aware of the current DM prevalence. Obesity was the most frequently identified risk factor for DM. Most comparisons indicated better awareness among health workers. Conclusion: A significant lack of knowledge about DM in Saudi society was identified. Social media and educational curriculum can improve knowledge and awareness of DM.

Summary Central diabetes insipidus (CDI) and several endocrine disorders previously classified as idiopathic are now considered to be of an autoimmune etiology. Dermatomyositis (DM), a rare autoimmune condition characterized by inflammatory myopathy and skin rashes, is also known to affect the gastrointestinal, pulmonary, and rarely the cardiac systems and the joints. The association of CDI and DM is extremely rare. After an extensive literature search and to the best of our knowledge this is the first reported case in literature, we report the case of a 36-year-old male with a history of CDI, who presented to the hospital’s endocrine outpatient clinic for evaluation of a 3-week history of progressive facial rash accompanied by weakness and aching of the muscles. Learning points: Accurate biochemical diagnosis should always be followed by etiological investigation. This clinical entity usually constitutes a therapeutic challenge, often requiring a multidisciplinary approach for optimal outcome. Dermatomyositis is an important differential diagnosis in patients presenting with proximal muscle weakness. Associated autoimmune conditions should be considered while evaluating patients with dermatomyositis. Dermatomyositis can relapse at any stage, even following a very long period of remission. Maintenance immunosuppressive therapy should be carefully considered in these patients.

Background and objectiveThis study aimed to determine the validity of using a single-question self-report of erectile dysfunction (ED) as a screening tool among Saudi men with type 2 diabetes mellitus (T2DM). Materials and methodsA cross-sectional study was conducted using a single-question self-report questionnaire to determine the association between the risk of ED and poor glycemic control among men with T2DM. The study was conducted in a hospital-based diabetes clinic in Riyadh, Saudi Arabia. Married adults (aged >18 years) suffering from T2DM for at least 1 year were included in the study. All statistical analy-ses were performed using SAS version 9.2 and R software (Foundation for Statistical Computing, Vienna, Austria). ResultsWith 86% response rate, 293 participants were included in this study. Over half (53.9%) of the partic-ipants were below 60 years of age. More than half (55.3%) were suffering from uncontrolled diabetes (i.e., HbA1c > 7%). There was significant correlation between the International Index of Erectile Function (IIEF) and self-reported question in terms of duration of T2DM (p < 0.001), type of treatment (p = 0.004), income of the participants (p = 0.005), age (p < 0.001), education level (p = 0.032), and occupation (p < 0.001). However, there was no significant correlation between IIEF and self-reported question in terms of body mass index (p = 743) and smoking. Regarding overall diagnostic accuracy of IIEF score to predict self-reported ED, receiver operating characteristic curve showed area under curve as 89.4%, which is sta-tistically significant. ConclusionSingle-question self-report of ED is a valid and reliable tool to screen diabetic patients suffering from sexual problems. Such tool may help to identify ED in diabetic patients and warrant early management.

The current recommended cutoff value for low vitamin D may result in overestimation of hypovitaminosis D. Vitamin D levels at 30.0 nmol/L can diagnose the hyperparathyroid cases leading to bone loss, with moderate accuracy, in the Saudi population. The new cutoff may help in identifying true cases that need clinical treatment and can reduce the burden on healthcare system. Different regions of the world have reported varying cutoff points as optimal values for vitamin D status to maintain bone health. A cross-sectional study comprising of interviews, anthropometrics, and blood samples was conducted in primary healthcare centers in Riyadh, Saudi Arabia. Standardized serum 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH) were measured using electrochemiluminescence immunoassays. Independent sample and paired sample t test were conducted to compare the true means. Pearson correlation co-efficient was calculated to measure the association between original and standardized 25(OH)D. Software program, MedCalc, was utilized to measure the receiver operating curve (ROC) for determining the optimal threshold value for vitamin D. The mean standardized 25(OH)D levels for 846 males and 1285 females were (32.0 ± 14.4 nmol/L vs 31.6 ± 16.7 nmol/L) respectively. Using the gold standard PTH cutoff > 6.9 pmol/L, the ROC had an optimal criterion value for males and females at 30.0 and 24.0 nmol/L, respectively. In the males, the sensitivity and specificity were 72% and 51%, whereas in females, it was 58.2% and 66.7%, respectively. The area under the curve (AUC) was at 0.62 and 0.65 (p

Type-2 diabetes (T2D) is associated in observational studies with both higher bone mineral density (BMD) and higher fracture risk for given BMD. These relationships may however be confounded by factors such as body mass index (BMI). Here we used Mendelian randomization (MR) to obtain non-confounded estimates of the effect of T2D and glycemic traits on BMD. We identified genetic variants strongly associated with T2D risk (34,840 T2D cases and 114,981 controls) and fasting glucose (133,010 nondiabetic individuals), but not associated with BMI, and determined the effects of these variants on BMD (up to 83,894 individuals). Using these variants as instrumental variables, we found that a genetically-increased risk of T2D increased femoral neck BMD (+0.034 SD in BMD per unit increase in log-odds of T2D [95% CI, 0.001 to 0.067; p = 0.044]). Genetically-increased fasting glucose also increased femoral neck BMD (+0.13 SD in BMD per mmol/L increase in fasting glucose [95% CI, 0.01 to 0.25; p = 0.034]). Similar nonsignificant trends were observed for the effects of T2D and fasting glucose on lumbar spine BMD. Our results indicate that both genetically-increased T2D risk and genetically-increased fasting glucose have weak positive effects on BMD. © 2016 American Society for Bone and Mineral Research.

Background: The study considered the long-term outcome of patients with papillary thyroid carcinoma treated with 30 mCi radioiodine. Objective: The aims of this study were to define and compare the remission rates of papillary thyroid carcinoma ablated with 30 mCi 131I prepared by either thyroid hormone withdrawal (THW) or recombinant human thyrotropin (rhTSH; Thyrogen®), and to identify variables predictive of a favorable prognosis. Method: An observational study was conducted at an academic medical center and a comparative summary of six studies is presented. Three hundred and seventy patients (THW group, n = 203; rhTSH group, n = 167) were recruited from a prospectively managed registry. The mean follow-up was 9.3 years (range 5.1–15.8 years) in the THW group and 7.1 years (range 5.0–9.7 years) in the rhTSH group. The primary endpoint was the long-term remission rates (no evidence of disease) in the THW group compared with the rhTH group. Results: The response at 12–18 months after 30 mCi remnant ablat...

The coronavirus disease of 2019 (COVID-19) pandemic significantly affected different life aspects, including healthcare communities and academic institutes. We aimed to assess the level of stress and risk factors among medical students and interns during the COVID-19 pandemic in the setting of the middle east respiratory syndrome -CoV endemic area.A questionnaire-based cross-sectional study was conducted on a randomly selected sample of medical students and interns. The questionnaire was anonymously self-administered to indicate perceive hygienic practice change, importance of viral prevention domestic hygiene, perceive adequacy of received information, perceived agreement to facilitators to alleviate covid stress, self-reported stress level, and generalized anxiety disorder score.A total of 322 returned the questionnaire (69.7% response rate). Participants had good knowledge regarding severe acute respiratory syndrome -CoV2 in multiple aspects, with an average score of 13.8 out of 14. Two-thirds (62.4%) of the students experienced mild anxiety, (23.9%) had moderate anxiety, (6.8%) had clinically high anxiety level, and another (6.8%) had a clinically very high anxiety level. The stress level, as reported by the respondents (on a 1-10 scale), showed a correlation with the Generalized Anxiety Disorder scale. We observed an increased level of social avoidance and hygienic practice facilitated by availability of hand sanitizers. Majority of the students receive information regarding COVID-19 from reliable and official resourcesMost students reported mild to moderate levels of anxiety, and was associated with enhancement of their universal precaution measures. The availability of alcohol-based hand sanitizers and the off-campus study were great relievers. The importance of reliable pandemic resources in educating students during pandemics is emphasized. Furthermore, this study indicate the importance of students' support services to address mental health and students' wellbeing in the era of pandemics.

Type 1 diabetes mellitus (T1DM) is quite prevalent in the world, with a proportion of 1 in every 300 persons and steadily rising frequency of incidence of about 3% every year. More alarmingly, the incidence of T1DM among infants is also increasing, with children as young as 6 months succumbing to it, instead of that at a rather established vulnerable age of around seven and near puberty, when the hormones antagonize the action of insulin. These reports pose a unique challenge of developing efficient T1DM management system for the young children. The Kingdom of Saudi Arabia (KSA) is the largest country in the Middle East that occupies approximately four-fifths of the Arabian Peninsula supporting a population of more than 33.3 million people, of whom 26% are under the age of 14 years. As per the Diabetes Atlas (8th edition), 35,000 children and adolescents in Saudi Arabia suffer from T1DM, which makes Saudi Arabia rank the 8th in terms of numbers of TIDM patients and 4th country in the world in terms of the incidence rate (33.5 per 100,000 individuals) of TIDM. However, in comparison with that in the developed countries, the number of research interventions on the prevalence, incidence, and the sociodemographic aspects of T1DM is woefully inadequate. In this review we discuss different aspects of T1DM in Saudi Arabia drawing on the published literature currently available.

In observational studies, type-2 diabetes (T2D) is associated with an increased risk of coronary heart disease (CHD), yet interventional trials have shown no clear effect of glucose-lowering on CHD. Confounding may have therefore influenced these observational estimates. Here we use Mendelian randomization to obtain unconfounded estimates of the influence of T2D and fasting glucose (FG) on CHD risk. Using multiple genetic variants associated with T2D and FG, we find that risk of T2D increases CHD risk (odds ratio (OR)=1.11 (1.05–1.17), per unit increase in odds of T2D, P=8.8 × 10−5; using data from 34,840/114,981 T2D cases/controls and 63,746/130,681 CHD cases/controls). FG in non-diabetic individuals tends to increase CHD risk (OR=1.15 (1.00–1.32), per mmol·per l, P=0.05; 133,010 non-diabetic individuals and 63,746/130,681 CHD cases/controls). These findings provide evidence supporting a causal relationship between T2D and CHD and suggest that long-term trials may be required to discern the effects of T2D therapies on CHD risk., In order to effectively design interventions, it is useful to understand the complex interplay between multiple syndromes. Here, Ahmad et al. use genome-wide association study data and Mendelian randomisation to examine the influence of Type 2 diabetes and fasting glucose levels on coronary heart disease.

AIM To determine the clinical and biological characteristics of double diabetes (DD) among young people in Saudi Arabia. METHODS This was a retrospective descriptive chart review study including 312 young newly diagnosed diabetic patients (aged 12-20 years), whom were admitted over a five year period (January 2009 to December 2013). Family history of diabetes mellitus (DM) (first degree), physical body mass index (BMI), acanthosis nigricans, history of auto-immune disease and laboratory information for glycosylated hemoglobin, basal C peptide level and diabetes autoantibody response (anti-GAD, anti-IA2 and anti-ICA) were collected from medical report. A mean follow-up of 3 years for these patients was performed. RESULTS Patients were categorized into 4 groups, based on the autoantibody response (Ab+ or Ab-) and C-peptide secretion (β+ for fasting level 0.4-2.1 ng/mL and β- if < 0.4 ng/mL). Group1 (type 1a): Ab+ β- (21%), group 2 (type 1b): Ab- β- (9%), group 3 (DD): Ab+ β+ (31%) and group 4 (classic type 2 DM): Ab- β+ (39%). The mean age of the DD patients in our study was 15.1 ± 6.4 years. A total of 41% of the study population presented with diabetic ketoacidosis and 61% of the study population presented with positive family history of DM. The mean BMI was 26.8 kg/m2 with 64% of overweight or obese patients. Ninety two percent of the patients were started on insulin at the time of diagnosis. During a mean follow-up of 3 years, only 32% of the patients with DD required insulin and 78% were on metformin alone or with insulin. CONCLUSION Our findings enable us to arrive at the conclusion that almost one-third of the young Saudi diabetic patients reveal atypical forms of DM (double diabetes) expressing features resulting from both T1D and T2D.
