Abstract
Metabolic syndrome, such as diabetes mellitus, obesity, atherosclerosis, and high blood pressure (HBP), are closely linked pathophysiologically. However, current monotherapies for metabolic syndrome fail to target the multifactorial pathology via multiple mechanisms, as well as resolving the dysfunctionality of the cells and organs of the body. We aimed to provide a comprehensive and up-to-date review of the pharmacological advances, therapeutic potential, and phytochemistry of Salvia miltiorrhiza, Carthamus tinctorius, and Danhong injection (DHI). We discussed the molecular mechanisms of the bioactive constituents relating to diabetes mellitus and metabolic disease for further research and drug development. Interestingly, Salvia miltiorrhiza, Carthamus tinctorius, and DHI have anti-inflammatory, anti-glycemic, anti-thrombotic, and anti-cancer properties; and they mainly act by targeting the dysfunctional vasculatures including the inflammatory components of the disease to provide vascular repair as well as resolving oxidative stress. The major bioactive chemical constituents of these plants include polyphenolic acids, diterpene compounds, carthamin, and hydroxysafflor yellow A. Treatment of diabetes mellitus and its associated cardiovascular complication requires a comprehensive approach involving the use of appropriate traditional Chinese medicine formula. Danshen, Honghua, and DHI target the multiple risk factors regulating the physiologic function of the body and restore normalcy, apart from the traditional advice on exercise and diet control as treatment options in a metabolic syndrome patient.

Bekele, BB
Diabetes & metabolic syndrome. 2019;(1):672-677
Abstract
BACKGROUND The prevalence of diabetes mellitus (DM) has been growing rapidly in the world. It is smashing particularly the lower and middle income countries (LMICs) severely. Due to its acute and chronic complications many lives have fallen under its bad shadow. Therefore, we aimed to review the existing evidence on major types and specific complications of DM among diabetic patients in Ethiopia. METHODS Both relevant quantitative and qualitative studies, conducted after 1990s, investigated and reported DM and complications from MEDLINE/PubMed, CINAHL, SCOPUS, DAOJ and Cochrane library databases were explored. In addition, System for Information for grey literature in Europe (SINGLE) database was investigated for the existence of unpublished grey literature. Total of 161 titles were identified and 17 studies met the inclusion criteria. Findings were narrated descriptively. RESULTS In this review 17 studies were included, and both macro and micro complications were summarized. Among the diabetic complications retinopathy, nephropathy, metabolic syndrome, impotence and depression were the main findings among diabetic patients in Ethiopia. CONCLUSION The burden of DM and its microvascular and macrovascular complications have been increasing among diabetic patients in Ethiopia. The increased duration of the diseases, lower socio economic level, existence of other complications, old age attributed the diabetic complications. Therefore, close monitoring and follow up of diabetic patients is necessary to reduce the incidence and prevalence of diabetic complications among the patients.

[Sex and gender-specific aspects in prediabetes and diabetes mellitus-clinical recommendations (Update 2019)].
Kautzky-Willer, A, Harreiter, J, Abrahamian, H, Weitgasser, R, Fasching, P, Hoppichler, F, Lechleitner, M
Wiener klinische Wochenschrift. 2019;(Suppl 1):221-228
Abstract
Metabolic diseases dramatically affect the life of men and women from infancy up to old age in different and manifold ways and are a major challenge for the healthcare system. The treating physicians are confronted with the different needs of women and men in the clinical routine. Gender-specific differences affect screening, diagnostic and treatment strategies as well as the development of complications and mortality rates. Impairments in glucose and lipid metabolism, regulation of energy balance and body fat distribution and therefore the associated cardiovascular diseases, are greatly influenced by steroidal and sex hormones. Furthermore, education, income and psychosocial factors play an important role in the development of obesity and diabetes differently in men and women. Males appear to be at greater risk of diabetes at a younger age and at a lower body mass index (BMI) compared to women but women feature a dramatic increase in the risk of diabetes-associated cardiovascular diseases after the menopause. The estimated future years of life lost owing to diabetes is somewhat higher in women than men, with a higher increase in vascular complications in women but a higher increase of cancer deaths in men. In women prediabetes or diabetes are more distinctly associated with a higher number of vascular risk factors, such as inflammatory parameters, unfavorable changes in coagulation and higher blood pressure. Women with prediabetes and diabetes have a much higher relative risk for vascular diseases. Women are more often morbidly obese and less physically active but may have an even greater benefit in health and life expectation from increased physical activity than men. In weight loss studies men often showed a higher weight loss than women; however, diabetes prevention is similarly effective in men and women with prediabetes with a risk reduction of nearly 40%. Nevertheless, a long-term reduction in all cause and cardiovascular mortality was so far only observed in women. Men predominantly feature increased fasting blood glucose levels, women often show impaired glucose tolerance. A history of gestational diabetes or polycystic ovary syndrome (PCOS) as well as increased androgen levels in women and the presence of erectile dysfunction or decreased testosterone levels in men are important sex-specific risk factors for the development of diabetes. Many studies showed that women with diabetes reach their target values for HbA1c, blood pressure and low-density lipoprotein (LDL)-cholesterol less often than their male counterparts, although the reasons are unclear. Furthermore, sex differences in the effects, pharmacokinetics and side effects of pharmacological treatment should be taken more into consideration.

Journal of diabetes and its complications. 2018;(3):271-278
Abstract
AIMS: Type 1 diabetic patients (T1DM) experience a higher cardiovascular disease and mortality risk than controls. We investigated whether visceral adipose tissue (VAT) contributes to coronary artery calcifications (CAC) and cardiac dysfunction in T1DM. METHODS A cross-sectional study of 118 T1DM patients without a history of cardiovascular disease (men/women: 68/50, age 46±12years, HbA1c 7.6±0.9%, BMI 25.8±4.1kg/m2) was conducted. CAC and VAT were measured using a CT scan. CAC was scored using the Agatston method. Cardiac functional abnormalities were assessed by echocardiography. RESULTS CAC scored ≥10 in 42% of patients. Systolic function was normal in all, but diastolic dysfunction was present in 75%. Forty-six percent had VAT≥100cm2. CAC score≥10 occurred more often in subjects with VAT≥100cm2 (54% vs 31%; p=0.01). Age (OR=1.10; p<0.0001), diabetes duration (OR=1.10; p=0.008), gender (OR=4.28; p=0.016), LDL-cholesterol (OR=1.03; p=0.009) and metabolic syndrome (OR=5.79; p=0.005) were independently associated with a CACS≥10. Subjects with CACS≥10 were more prone to have diastolic dysfunction (84 vs 54%; p=0.03). Factors independently associated with diastolic dysfunction were age (OR=1.11; p=0.002), waist circumference (OR=1.10; p=0.016) and VAT (OR=0.99; p=0.035). CONCLUSIONS Excess VAT in T1DM, present in 46%, is associated with diastolic dysfunction and CAC, present in respectively 75% and 42% of patients. Timely detection might improve future cardiovascular risk.

Alabbood, MH, Ho, KW, Simons, MR
Diabetes & metabolic syndrome. 2017;(1):83-87
Abstract
BACKGROUND Ramadan fasting is one of the five pillars of Islam. People with diabetes are exempted from fasting according to Islamic rules. However, many people with diabetes wish to fast. Physicians are asked frequently by their patients about their ability to fast and the possible impact of fasting on their glycaemic control. Studies about the effect of Ramadan on people with insulin-treated diabetes are scarce. This review aims to provide clinicians with the best recommendations for their patients with insulin-treated diabetes who wish to fast. METHODS Four databases (Medline, EMBASE, Scopus and PubMed) were searched using the following MeSH terms and keywords: "insulin dependent diabetes mellitus", "type 1 diabetes mellitus", 'Ramadan' "and" "fasting". In addition, a hand search of key journals and reference lists was performed. Sixteen full text articles were selected for review and critical analysis. RESULTS All of the included studies except one found improvement or no change in glycaemic control parameters during Ramadan fasting. The incidence of major complications were negligible. Minor hypoglycaemic events were reported in some studies but did not adversely affect fasting. Postprandial hyperglycaemia was a major concern in other studies. However, the incidence of severe hyperglycaemia and diabetic ketoacidosis were trivial. CONCLUSION Ramadan fasting is feasible for insulin dependent diabetic patient who wish to fast. Clinicians should advise their patients about the importance of adequate glycaemic control before Ramadan and frequent glucose monitoring during fasting. Certain types of Insulin seem to be more beneficial than other.

[Diabetic eye disease].
Henriques, J, Vaz-Pereira, S, Nascimento, J, Rosa, PC
Acta medica portuguesa. 2015;(1):107-13
Abstract
Diabetes mellitus is a chronic metabolic disease characterized by sustained hyperglycemia leading to macro and microvascular complications. The eye is one of the main organs affected by this disease, being diabetic retinopathy the most well-known microvascular complication and the leading cause of blindness in the working age population. However, diabetic ocular disease is not only characterized by diabetic retinopathy. Other important ocular manifestations of diabetes mellitus include cataract, glaucoma, ischemic optic neuropathy, cranial nerve palsies and recurrent corneal erosion syndrome. Here, we emphasize diabetic retinopathy as the most important and characteristic complication of diabetes mellitus, but also review less well-known complications with the aim to alert and sensitize non-ophthalmologist clinicians that treat diabetic individuals, in order to promote an early diagnosis and treatment of the sight-threatening complications of diabetes.

Bener, A, Al-Laftah, F, Al-Hamaq, AO, Daghash, M, Abdullatef, WK
Diabetes & metabolic syndrome. 2014;(2):108-14
Abstract
AIM: The aims of this study were to determine the prevalence of diabetic complications namely neuropathy, nephropathy, and retinopathy among Qatari's DM patients; and to find associations between these complications and socio-demographic and clinical characteristics in a highly consanguineous population. DESIGN It is an observational cohort study. SETTING The survey was carried out at the Hamad General Hospital and Primary Health Care (PHC) centers in the State of Qatar. SUBJECTS The study was conducted from May 2011 to January 2013 among Qatari nationals above 20 years of age. Of the 2346 registered with diagnosed diabetes attending Hamad General Hospital and PHC centers, 1633 (69.3%) agreed and gave their consent to take part in this study. METHODS Questionnaire included socio-demographic variables, body mass index (BMI), consanguinity, lifestyle habits, family history of diabetes, blood pressure and development of diabetes complications such as retinopathy, nephropathy, and neuropathy were collected at regular intervals throughout the follow-up. Univariate and multivariate statistical analysis were performed. RESULTS Out of 1633 diabetic patients, 842 (51.6%) were males. The prevalence of diabetic nephropathy 12.4% and retinopathy was 12.5% followed by neuropathy 9.5% among diabetic population. The proportion of diabetic neuropathy and nephropathy were significantly higher among diabetic patients with age 60 years and above as compared to younger age groups (p=0.010). Nephropathy was significantly higher among male diabetic (p=0.014) and smokers (p<0.001) while diabetic neuropathy was more common among diabetic hypertensive patients (p=0.028). Multivariate logistic regression showed that Age (p=0.025), being male (p=0.045), and having high blood pressure (p=0.006) were significant predictors of diabetic neuropathy. For diabetic retinopathy, family history of DM (p<0.001), consanguinity (p=0.010), having high blood pressure (p=0.042) and physical activity (p<0.001) were significant predictors of diabetic retinopathy. Meanwhile, for diabetic nephropathy, age (p<0.001), smoking (p=0.045), physical activity (p<0.001) hypertension (p<0.001) and gender (p=0.012) were the significant predictors. CONCLUSION Diabetes exerts a significant burden in Qatar, and this is expected to increase. Many diabetic patients face significant challenges accessing diagnosis and treatment, which contributes to the high morbidity and mortality and prevalence of complications observed. The significant interactions between diabetes and associated complications highlight the need and opportunity for health planners to develop integrated responses to communicable and non-communicable diseases.

The association between renal stone disease and cholesterol gallstones: the easy to believe and not hard to retrieve theory of the metabolic syndrome.
Ahmed, MH, Barakat, S, Almobarak, AO
Renal failure. 2014;(6):957-62
Abstract
Renal stone disease and gallstone disease are widely prevalent and costly disease across the globe. Both renal stone disease and gallstone disease are associated with a variety of diseases including obesity, metabolic syndrome, dyslipidemia, hypertension, insulin resistance diabetes and gout. Importantly, the presence of either renal stone disease or gallstone disease is associated with an increased risk of cardiovascular disease. In a recent study of the Atherosclerosis Risk in Communities (ARIC), individuals with a history of gallstones were 54% more likely to report a history of nephrolithiasis after adjusting for age, gender, body size and other factors. Furthermore, in three large cohorts including over 240,000 subjects: the Nurses' Health Studies (NHS) I and II and the Health Professionals Follow-up Study (HPFS), showed that gallstone disease is independently associated with nephrolithiasis. The mechanisms linking gallstone disease and renal stone disease are complex and not yet established. Insulin resistance, lithogenic diets, alterations of transporters in gallbladder and urinary system, and pH are possible potential mechanisms for future exploration. How the liver communicates with kidney in individuals with renal stone disease and gallstone disease is not well known and whether this communication is similar as in hepto-renal syndrome is subject for future research. Further research is needed to determine: (i) the underlying mechanisms of renal stone disease and gallstone disease; (ii) the potential treatment of renal stone disease and gallstone disease.
