Trends of microplastic abundance in personal care products in the United Arab Emirates over the period of 3 years (2018-2020).

Plastic microbeads in cosmetic products are considered one of the main contributors of primary microplastic pollution in aquatic environments. To assess the trends of microplastic usage in rinse-off cosmetic products over the last 3 years in the United Arab Emirates (UAE), 163 body scrub and face wash products were randomly selected and purchased from different UAE markets over a period of two (2019 and 2020) consecutive years as a continuation of our study of such products in 2018. Microbeads were extracted from the products and their composition was determined. The comparative analysis of the products revealed the presence of microplastic content in fewer products in 2019 and 2020 than to 2018. The results revealed that some of the products that contained microplastic in 2018 still have them in 2020. However, no new products were found on the market that contained microplastic. Overall, fewer products contained microbeads of any composition. Also, the consumer awareness, preferences, and behavior towards microplastic use in personal care products was assessed through a survey 2020 that complemented a survey carried out in 2018. An increasing awareness among the surveyed general public was noted regarding microplastic use in cosmetics and its adverse effects to the environment. The study indicates that an increasing global legislation is effective to curtail the use of microplastic containing microbeads in personal care products by replacing them with beads of alternative composition or avoiding the use of microbeads altogether. Nevertheless, products having microplastic content in the UAE were found to be imported or manufactured by companies based in countries where microplastic usage in personal care products has already been banned by law.

Frequency of non-alcoholic fatty liver disease (NAFLD) and its associated risk factors among Type-2 diabetics.

OBJECTIVES: To determine the frequency of Non-Alcoholic Fatty Liver Disease (NAFLD) and its associated risk factors among Type-2 Diabetic patients. METHODS: This cross-sectional study was conducted in Diabetic Clinic of Shaikh Zayed Postgraduate Medical Institute Lahore from September 2019-February 2020. Type-2 diabetics regardless of age were divided into two groups, one with fatty liver disease and the other without this, evaluated by Abdominal Ultrasonography and were further evaluated by measurement of BMI, obesity, HbA1c and lipid profile. Exclusion criteria were patients having history of or currently taking alcohol, chronic Liver Disease of any cause and intake of hepatotoxic drugs. Qualitative measures were compared between groups by using Chi-square test. Binary logistic regression was used to see the association of factors with fatty liver disease. P-value ≤ 0.05 was considered significant. RESULTS: A total of 185 subjects were included in the study with the mean age of 53.0±9.0 years. About 54.6% patients were diagnosed to have fatty liver disease. When compared the cases with and without fatty liver disease, age and HDL cholesterol had no significant difference between groups while other measures like BMI, TGs & cholesterol levels, ALT and AST were significantly higher among cases with NAFLD. BMI >24.5, HbA1c >7.0 and ALT >40.0 can predict NAFLD among Type-2 diabetic patients with 96.8% accuracy. CONCLUSION: There is high prevalence of NAFLD among Type-2 diabetic patients and strong association between Type-2 diabetics with NAFLD and risk factors like; obesity, high HbA1c, hyperlipidemia and high ALT. Therefore, early recognition by ultrasonography in high risk patients and intervention like life style modification, maintenance of healthy weight, obesity prevention, treatment of dyslipidemia and good glycemic control should be achieved in such subjects and can prevent NAFLD.

Lessons of the month 2: Retinal vasculitis: a first presentation of Takayasu's arteritis.

Takayasu's arteritis is a chronic, systemic, large-vessel vasculitis affecting the aorta and its primary branches. However, coronary, renal and pulmonary arteries and small vessel involvement has been documented. We describe a rare case of Takayasu's arteritis with extensive supra-aortic arch disease, manifesting with bilateral occlusive retinal vasculitis as a first presentation. This is elicited by fundus findings of vascular sheathing and fundus fluoresceine angiography evidence of retinal vessel occlusion and peripheral capillary non-perfusion.

Frequency of impaired fasting glucose in first degree relatives of Type-II diabetic patients and its association with Body Mass Index.

OBJECTIVES: To determine the frequency of impaired fasting glucose in first degree relatives of people with Type-II diabetes and its association with BMI. METHODS: This cross-sectional study was conducted in Diabetic clinic of Shaikh Zayed Hospital, Lahore from July to December 2017. Individuals aged ≥35 years, first degree relatives of people with Type-II diabetes, were selected and their fasting blood glucose levels were checked twice a week apart. Study participants were divided into 3 groups. Group-I were those with normal fasting blood glucose (FBS: <100mg/dl), Group-II were those with impaired fasting glucose (100-125mg/dl), considered as high risk and Group-III included those who turned out to be having frank diabetes (FBS: ≥126mg/dl). Exclusion criteria were known diabetes and pregnancy. Proportions of impaired fasting glucose levels versus BMI were compared using Chi-square test. Significance was considered at P <0.001. RESULTS: A total of hundred subjects were included in the study with the mean age of 44.27 years. Sixty percent participants had normal FBS, 31% showed impaired FBS and 09% had frank diabetes (P <0.001). Significant association was found between impaired fasting glucose and BMI, as with increasing BMI the frequency of impaired fasting glucose increases. CONCLUSION: First-degree relatives of people with Type-II diabetes showed higher frequency of impaired fasting glucose and obesity was an important risk factor.

Parathyroid Gland Response to Vitamin D Deficiency in Type 2 Diabetes Mellitus: An Observational Study.

Background Studies have linked vitamin D deficiency with the risk of type 2 diabetes mellitus (T2DM) and to the development of chronic complication of diabetes. Vitamin D receptors (VDR) have been found in many tissues in the body including the pancreas, a finding that indicates its role in insulin secretion. In addition, many studies have demonstrated the role of vitamin D and its receptor in insulin sensitivity and signal transduction. Vitamin D deficiency is common throughout the world, but not all vitamin D deficiencies are accompanied by a rise in parathyroid hormone (PTH). The present study was conducted to assess vitamin D deficiency in type 2 diabetic patients in comparison to healthy control and to determine parathyroid gland response to vitamin D deficiency in both groups. Methods This observational study was performed during a period from January to October 2018. The study included 151 type 2 diabetic patients selected from three diabetes clinics and 43 age and sex-matched healthy subjects. Informed consent and clinical information were obtained from all participants before the study. Results of the laboratory analysis for serum 25-hydroxyvitamin D (25-OHD), PTH, calcium, and phosphorous were recorded. The data was analyzed using the statistical package for the social sciences (SPSS) Statistics 17. Results The results showed low vitamin D concentration in both groups; however, there was no significant difference in vitamin D concentration between diabetic patients and the control patients. A high percentage of PTH level was found in severe vitamin D deficient diabetic patients and healthy controls. The higher percentage of diabetic and normal subjects with mild vitamin D deficiency had a normal PTH level. All healthy subjects with vitamin D insufficiency showed normal PTH concentration. About 10% of diabetic patients with severe vitamin D deficiency had a low PTH level. Conclusion The population in our study was generally deficient in 25-OHD irrespective of diabetes mellitus, indicating a greater need for vitamin D supplementation. Not all vitamin D deficient patients have high PTH levels, a finding that supports the emergence of new criteria for vitamin D deficiency, diagnosis and treatment, and highlights the importance of testing PTH in this regard.

Correlation between Microalbuminuria and Hypertension in Type 2 Diabetic Patients.

BACKGROUND: Hypertension is commonly found in patients with Diabetic Kidney Disease (DKD). Microalbuminuria is the first clinical sign of involvement of kidneys in patients with type 2 diabetes. Uncontrolled hypertension induces a higher risk of cardiovascular events, including death, increasing proteinuria and progression to kidney disease. OBJECTIVES: To determine the correlation between microalbuminuria and hypertension and their association with other risk factors in type 2 diabetic patients. METHODS: One hundred and thirteen type 2 diabetic patients attending the diabetic clinic of Shaikh Zayed Postgraduate Medical Institute, Lahore, Pakistan were screened for microalbuminuria and raised blood pressure. The study was conducted from November 2012 to June 2013. RESULTS: Patients were divided into two groups. Group 1, those with normoalbuminuria (n=63) and Group 2, those having microalbuminuria (n=50). Group 2 patients showed higher blood pressure values as compared to Group 1. The results were statistically significant and showed poor glycemic control as a contributing risk factor. CONCLUSION: The study concluded that there is high frequency of hypertension among type 2 diabetics but still much higher among those having microalbuminuria. So, early recognition of renal dysfunction through detection of microalbuminuria and to start treatment without any delay will confer future protection from end stage renal disease as well as hypertension and its complications in type 2 diabetic patients.

Lupus catatonia in a young girl who presented with fever and altered sensorium.

We report a case of 20 Years old girl who presented with catatonia resulting from cerebral lupus. There are few cases of catatonia being described in Systemic Lupus Erythmatoses (SLE). The patient presented to us with fever and altered sensorium. She was initially treated on lines of Acute Bacterial Meningitis/encephalitis but lumbar puncture examination and CT scan showed no evidence of these conditions. Patient's behavior was also not improved after this treatment and she further deteriorated in the sense that she exhibited mutism, negativism and psychosocial withdrawal. Psychiatric analysis was done and she was found to be having catatonia and on further investigation came out to be a case of SLE. Keeping in mind her previous history of joint pains, oral ulcers and alopecia her autoimmune profile such as ANA and dsDNA was done that came out to be positive. Patient responded to treatment with steroids, Hyroxychloroquine and azathioprine in addition to clonazepam and fluoxetine for her catatonic behavior. Thus this case history illustrates the importance of considering organic disease in patients presenting with catatonia.

Prevalence of microvascular complications in newly diagnosed patients with type 2 diabetes.

BACKGROUND & OBJECTIVE: Microvascular complications are the major outcome of type 2 Diabetes Mellitus progression, which reduce the quality of life, incur heavy economic burdens to the health care system and increase diabetic mortality. The aims of this study were to assess the prevalence of microvascular complications among newly diagnosed type 2 diabetic patients and to analyze the association between these complications and poor glycemic control. METHODS: This cross sectional hospital based study was carried out in Diabetic Clinic of Shaikh Zayed Postgraduate Medical Institute, Lahore Pakistan. The study was conducted from November 2011 to November 2012 among newly diagnosed type 2 diabetic patients. Relevant information of all patients was recorded with the help of a proforma. They were investigated for retinopathy, nephropathy and neuropathy. RESULTS: We have divided the patients into two groups: Group I with good glycemic control (HbA1c <6.5) and group II with poor glycemic control (HbA1c >6.5). In group II microvascular complications were 89.8%. Neuropathy, nephropathy and retinopathy were present in 68.5%, 56.2% and 31.4% respectively. These similar percentages in Group I were 50%, 0% and 31% respectively and are significantly lower. CONCLUSION: The study showed that even in newly diagnosed type 2 diabetic patients who had poor glycemic control, frequency of microvascular complications is much higher as compared to those who had average glycemic control. Thus tight glycemic control does count even in newly diagnosed type 2 diabetics to prevent and minimize the occurrence of complications.

Systematic review of the agreement of tonometers with Goldmann applanation tonometry.

OBJECTIVE: To assess the agreement of tonometers available for clinical practice with the Goldmann applanation tonometer (GAT), the most commonly accepted reference device. DESIGN: A systematic review and meta-analysis of directly comparative studies assessing the agreement of 1 or more tonometers with the reference tonometer (GAT). PARTICIPANTS: A total of 11 582 participants (15 525 eyes) were included. METHODS: Summary 95% limits of agreement (LoA) were produced for each comparison. MAIN OUTCOME MEASURES: Agreement, recordability, and reliability. RESULTS: A total of 102 studies, including 130 paired comparisons, were included, representing 8 tonometers: dynamic contour tonometer, noncontact tonometer (NCT), ocular response analyzer, Ocuton S, handheld applanation tonometer (HAT), rebound tonometer, transpalpebral tonometer, and Tono-Pen. The agreement (95% limits) seemed to vary across tonometers: 0.2 mmHg (-3.8 to 4.3 mmHg) for the NCT to 2.7 mmHg (-4.1 to 9.6 mmHg) for the Ocuton S. The estimated proportion within 2 mmHg of the GAT ranged from 33% (Ocuton S) to 66% and 59% (NCT and HAT, respectively). Substantial inter- and intraobserver variability were observed for all tonometers. CONCLUSIONS: The NCT and HAT seem to achieve a measurement closest to the GAT. However, there was substantial variability in measurements both within and between studies.
