Preliminary study on the effect of ozone exposure on blood glucose level in rats.

BACKGROUND: In recent years, people have paid more and more attention to the health hazards caused by O3 exposure, which will become a major problem after fine particulate matter (PM). OBJECTIVE: To investigate the effects of ozone (O3) exposure on blood glucose levels in rats under different concentrations and times. METHODS: Eighty rats were divided into control group and three ozone concentration groups. Each group was continuously exposed for 1d, 3d and, 6d, and exposed for 6 hours daily. After exposure, GTT, FBG, and random blood glucose were measured. RESULTS: The FBG value increased significantly on the 6th day of 0.5 ppm and the 3rd and 6th days of 1.0 ppm exposure compared with the control group (P< 0.05). The random blood glucose value was significantly increased on the 3rd and 6th days of each exposure concentration (P< 0.05). When exposed to 1 ppm concentration, the 120 min GTT value of 1 d, 3 d and, 6 d was significantly higher than that of the control group (P< 0.05). CONCLUSION: After acute O3 exposure, the blood glucose level of rats was affected by the exposure concentration and time. The concentration of 0.1 ppm had no significant impact on FBG and random blood glucose, and O3 with a concentration of 0.1 ppm and 0.5 ppm had no significant impact on values of GTT at 90 min, and 120 min.

Random Blood Glucose, but Not HbA1c, Was Associated with Mortality in COVID-19 Patients with Type 2 Diabetes Mellitus-A Retrospective Study.

Previous studies have yielded inconsistent results on whether glycated hemoglobin (HbA1c) and random blood glucose (RBG) are associated with mortality of coronavirus disease 2019 (COVID-19) patients with type 2 diabetes mellitus (T2DM). This study aimed to assess the association of HbA1c and RBG with mortality among COVID-19 patients with T2DM. A retrospective study was conducted on 237 patients with COVID-19 and T2DM (survival (n = 169) and non-survival groups (n = 68)). Data on socio-demography, comorbidities, clinical symptoms, laboratory examination, and mortality were collected. Patients in the non-survival group had an older age range as compared with those in the survival group (60 (52.3-65.0) vs. 56.0 (48.5-61.5) years, p = 0.009). There was no statistical gender difference between the two groups. After matching was done, chronic kidney disease, NLR, d-dimer, procalcitonin, and random blood glucose were higher in the non-survival group compared to the survival group (p < 0.05). HbA1c levels were similar in survivors and non-survivors (8.7% vs. 8.9%, p=0.549). The level of RBG was independently associated with mortality of COVID-19 patients with T2DM (p = 0.003, adjusted OR per 1-SD increment 2.55, 95% CI: 1.36-4.76). In conclusion, RBG was associated with the mortality of COVID-19 patients with T2DM, but HbA1c was not.

Comparative Analysis of Glycemic and Lipid Profiles in Newly Diagnosed Males and Females With Type 2 Diabetes Mellitus.

Background Age- and gender-based differences in diabetes demographic characteristics have been studied in many types of research. These differences extend further to diabetes-related comorbidities. Dyslipidemia is a common complication associated with diabetes and causes a substantial increase in cardiovascular morbidity. The study aims to compare the pattern of dyslipidemia between males and females among different age categories in newly diagnosed type 2 diabetes mellitus (T2DM). Methodology A retrospective database study was conducted at Faiha Specialized Diabetes, Endocrine, and Metabolism Center (FDEMC), Basrah, Southern Iraq. We included adult patients with newly diagnosed and drug naïve T2DM between January 2018 and October 2022. Patients' data in the form of body mass index (BMI), hemoglobin A1c (HbA1c), fasting blood glucose (FBG), random blood glucose (RBG), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were used for comparisons. Results Below the age of 35, males exhibited significantly higher levels of HbA1c, FBG, and TG compared to females, along with a significantly lower level of HDL-C. However, there were no significant differences in BMI, RBG, TC, and LDL-C. Between the ages of 35 and 44, females in this study demonstrated significantly higher BMI and HDL-C levels, while males exhibited higher levels of HbA1c, FBG, RBG, and TG. However, there were no significant differences observed in TC and LDL-C levels. Similar results were found among the age group 45 to 55, with the only exception being FBG, which became nonsignificant. In patients between 55 and 64 years old, BMI, HDL-C, and TC were significantly higher in females (P < 0.05). In patients aged above 65 years, BMI and HDL-C remained significantly higher in females, while RBG was significantly higher in males. No significant differences were observed among other parameters (HbA1c, TG, TC, and LDL-C). Conclusions In patients aged 54 years and younger, males were significantly more likely to have severe hyperglycemia, higher TG, and lower HDL-C compared to females at the time of T2DM diagnosis. In older patients, this pattern is lost, with only a significantly lower HDL-C observed.

Visceral Adiposity Index: A Simple Tool For Assessing Risk Of Type 2 Diabetes Mellitus.

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) has increased recently in Pakistan. Visceral adiposity index (VAI) appears to be a better predictor for metabolic syndrome associated with insulin resistance. VAI has been shown to be linearly and positively associated with diabetes mellitus (DM) in many populations. It is, however, uncertain whether VAI could be associated with T2DM in the Pakistani adult population.. METHODS: This is a cross-sectional study of 300 outpatients with a newly diagnosed T2DM. Subjects were recruited from Lady Reading Hospital, Pakistan, during the period from April, 2020 to January, 2021. For all study subjects, anthropometric measurements were performed. Blood samples were collected for the assessment of high-density lipoproteins (HDL-C), triglycerides (TGs), glycated hemoglobin (HbA1c), and random blood glucose. RESULTS: Participants with high VAI showed poor glycemic control. The number of patients with poor glycemic control increased across the VAI quartiles. VAI showed significant correlations with TGs (r=0.715, p=<0.001), total cholesterol (TC) (r=0.256, p=<0.001), low density lipoprotein (LDL-C) (r=0.154, p=0.007), uric acid (r=0.205, p=0.019), duration of diabetes (r=0.171, p=0.033), TSH (r=0.163, p=0.007), and random blood glucose (r=0.195, p=0.019). CONCLUSIONS: Our data suggest that VAI is significantly and positively correlated with the risk factors of DM such as random blood glucose, uric acid and TSH. The findings of the study do not imply a significant direct association between VAI and DM among the Pakistani adult population. Prospective-large scale studies can help inform an effectiveness of VAI for the prediction of the risk of T2DM among Pakistani population.

Nontraditional risk factors of coronary artery disease among Palestinians: A case-control study.

BACKGROUND: Coronary Artery Disease (CAD) is one of the most common causes of death in Palestine. This study aimed to assess the nontraditional risk factors among CAD patients underwent invasive coronary angiography in Gaza-Palestine. METHODS: Unmatched one-to-one case-control study was conducted among 200 participants. Cases were recruited from newly discovered CAD patients after a confirmed diagnosis of CAD by interventional cardiologist post catheterization "coronary angiography" in Al-Shifa Cardiovascular Catheterization Center. Controls were enrolled from individuals with no history of CAD. An interview-based questionnaire was used to assess patient's characteristic data and medical history; anthropometric, and the Ankle Brachial Index(ABI) was measured and calculated. Furthermore, biochemical analysis of high sensitivity C-reactive protein (hs-CRP) level and Random blood glucose level (RBG) and Leukocyte count (WBCs)were investigated. All required ethical approvals were obtained. Data were managed and analyzed by STATA version 14. Correlation analysis by multivariate logistic regression was done. RESULTS: hs-CRP, RBG, and WBCs remained significant predictors for CAD adjusted for age, education level, employment status, and monthly income. As, the odds of CAD increased by 3% for each unit increased in hs-CRP (Odd Ratio (OR)=1.03; 95% confidence interval (CI):1.01, 1.06; P = 0.020); and the odds of CAD was augmented by 30% for each unit increased in WBCs (OR= 1.30; 95% CI: 1.07, 1.67; P = 0.010); While the odds of CAD was 5 times more for each unit increased in RBG (OR=5.04; 95% CI: 1.17, 14.88; P = 0.003). Still, age remained a significant risk factor as the odds of CAD was 19% more for each increased year in age (OR=1.19; 95%CI: 1.13, 1.26; P<0.001). CONCLUSION: Nontraditional factors (hs-CRP, RBG, and WBCs) are significant predictors of CAD, and should be considered in adult patients coming with attacks of angina pain.

Admission Random Blood Glucose, Fasting Blood Glucose, Stress Hyperglycemia Ratio, and Functional Outcomes in Patients With Acute Ischemic Stroke Treated With Intravenous Thrombolysis.

BACKGROUND: Stress hyperglycemia ratio (SHR), calculated as glucose/glycated hemoglobin, has recently been developed for assessing stress hyperglycemia and could provide prognostic information for various diseases. However, calculating SHR using random blood glucose (RBG) drawn on admission or fasting blood glucose (FBG) could lead to different results. This study intends to evaluate the association between SHR and functional outcomes in patients with acute ischemic stroke (AIS) with recombinant tissue plasminogen activator (r-tPA) intravenous thrombolysis. METHODS: Data from 230 patients with AIS following thrombolytic therapy with r-tPA in the Third Affiliated Hospital of Wenzhou Medical University from April 2016 to April 2019 were retrospectively reviewed. SHR1 was defined as [RBG (mmol/L)]/[HbA1c (%)] and SHR2 was defined as [FBG (mmol/L)]/[HbA1c (%)]. The outcomes included early neurological improvement (ENI), poor function defined as a modified Rankin Scale score (mRS) of 3-6, and all-cause death in 3 months. Multivariable logistic regression was performed to estimate the association between SHR and adverse outcomes. RESULTS: After adjustment for possible confounders, though patients with AIS with higher SHR1 tend to have a higher risk of poor outcome and death and unlikely to develop ENI, these did not reach the statistical significance. In contrast, SHR2 was independently associated with poor functional outcome (per 0.1-point increases: odds ratios (OR) = 1.383 95% CI [1.147-1.668]). Further adjusted for body mass index (BMI), triglyceride-glucose index (TyG), and diabetes slightly strengthen the association between SHR (both 1 and 2) and adverse outcomes. In subgroup analysis, elevated SHR1 is associated with poor functional outcomes (per 0.1-point increases: OR = 1.246 95% CI [1.041-1.492]) in non-diabetic individuals and the association between SHR2 and the poor outcomes was attenuated in non-cardioembolic AIS. CONCLUSION: SHR is expected to replace random or fasting glucose concentration as a novel generation of prognostic indicator and a potential therapeutic target.

Evaluation of Indian Diabetes Risk Score and Random Blood Sugar Testing for Opportunistic Screening of Type 2 Diabetes Patients at a District Hospital of Gujarat.

Background: India is home to 69.2 million diabetics. For opportunistic screening of type 2 diabetes mellitus (DM), random capillary blood sugar (RBS) testing is used. Another method is Indian Diabetes Risk Score (IDRS), which is a simple and cost effective method for opportunistic screening of type 2 DM patients. The aim is to evaluate the screening test parameters of RBS testing and IDRS for opportunistic screening of undiagnosed type 2 DM patients. Materials and Methods: A cross-sectional study was done during February 2017 to August 2017 at a district hospital of Western Gujarat. A sample size of 317 patients was calculated using Buderer's formula. Systematic random sampling was used and every third patient was selected from the general Outpatient Department(OPD) attendees of 30 years or more. MS Excel and Epi Info v7.2 was used for statistical analysis. Screening parameters and accuracy of IDRS and RBS were calculated taking result of the oral glucose tolerance test as clinical reference. Results: The mean age of study participants was 50.9 (SD 12.17) years with 44.2% males and 55.8% females. Sensitivity and specificity of RBS was 72.4% and 69.1%. Sensitivity and specificity of IDRS was 93.1% and 29.0%. On simultaneous (parallel) screening by IDRS and RBS, sensitivity was 98.3% and specificity was 23.2%. In sequential screening, where IDRS was used followed by RBS, sensitivity was 67.2% and specificity was 74.9%. Conclusions: This study has found that sequential screening using a simple diabetes risk score like IDRS followed by RBS is having higher accuracy and reduced cost of opportunistic screening of type 2 diabetes. Adopting sequential screening using IDRS as first step of screening followed by RBS in those found as high risk by IDRS is recommended.

Are patients affected by chronic non-communicable diseases aware of their own clinical and laboratory parameters? A cross-sectional study from the south of Saudi Arabia.

BACKGROUND: Patient's awareness of their clinical and laboratory parameters is an indicator of the degree of involvement in achieving their management goals. This investigation aimed to identify awareness of patients affected by chronic non-communicable diseases of their clinical and laboratory parameters and factors associated with the awareness. METHODS: This study was a cross-sectional investigation conducted in the Jazan region, between January and August 2020. Data was collected during phone interviews utilizing a semi-structured questionnaire. Odds ratios (ORs) were calculated to estimate the likelihood of awareness of each clinical and laboratory parameter according to the measured demographic variables. RESULTS: The total number of recruited patients was 675. The mean age of participants was 53.7 years and the 28.7% of patients were illiterate. About 17% of the patient do not attend follow-up visits to any healthcare provider. When patients were asked about their parameters, 87% of them were able to report their body weight and 74% were able to report their height. However, less than half of patients were aware of their glycated hemoglobin level (HbA1c) (271/675 patients) and systolic blood pressure (BP) level (329/ 675 patients), and a minority were aware of their total cholesterol level (71/675 patients). Being female, resident in a rural area, illiterate, and older than 53 was strongly associated with high odds of limited awareness about their own clinical and laboratory parameters (P values < 0.05). CONCLUSION: Awareness of patients affected by chronic non-communicable diseases of their own clinical and laboratory parameters in the Jazan region is sub-optimal where this limited awareness is likely to be associated with the lower engagement of patients with achieving their desired management targets.

Relationship of surfactant protein-D with random blood glucose and extra pulmonary infections in type-2 diabetes mellitus.

OBJECTIVES: To compare surfactant protein-D levels in type 2 diabetics and non-diabetics, and to explore its link with random blood glucose and extra-pulmonary infections. METHODS: The case-control study was conducted in 2012-13 at the Dow University of Health Sciences, Karachi, and comprised diabetic cases and non-diabetic controls. Extra pulmonary infections, body mass index and random blood glucose levels were noted and serum surfactant protein-D was analysed using enzynme-linked immunosorbent assay. Data was analysed using SPSS 20. RESULTS: Of the 120 subjects, 60(50%) each were cases and controls. Significant negative correlation was found between surfactant protein-D and infections (rs= -0.495, p=0.0001). A negative association between random blood glucose and surfactant protein-D was found, but it was not significant (p=0.15). Relative risk for extra-pulmonary infections in diabetics was 2 times higher than the controls (odds ratio: 2.10, p=0.04). CONCLUSIONS: Serum surfactant protein-D was found to have negative association with extra-pulmonary infections.

Coronavirus disease 19 and risk of hyperglycemia among Iraqi patients.

A cross-sectional observational study was conducted on 213 patients with COVID-19 who did not have a clinical history of diabetes at hospital admission. One week after hospitalization, they were stratified by random blood glucose levels. It was found that 25.4, 22.5 and 52.1% of COVID-19 patients were classified as normoglycemia, prediabetes and diabetes, respectively. The study indicated that diabetes may be a risk factor for COVID-19 or the disease may be associated with an increased risk of developing diabetes.

A Retrospective Multicenter Study on the Usefulness of 50 g Glucose Challenge Test in Gestational Diabetes Mellitus Screening.

INTRODUCTION: To clarify the usefulness of glucose challenge test (GCT), the rate of gestational diabetes mellitus (GDM) detection and perinatal outcomes were compared between the groups of random blood glucose level (RBG) and 50 g GCT in this study. METHODS: The first survey was conducted at 255 institutions registered by the Kanto Society of Obstetrics and Gynecology and clinical training institutions in the Kanto Area, followed by a second survey. The included women were broadly classified into the RBG and GCT groups, according to the mid-trimester blood glucose screening method, and the perinatal outcomes of the two groups were retrospectively compared. The primary outcomes were the proportion of infants weighing 3,500 g or more and birth weight ≥90th-percentile infants. RESULTS: The rate of GDM diagnosis was significantly higher in the GCT group (7.6%) than that in the RBG group (4.8%). However, no significant differences were observed in perinatal outcomes, i.e., the proportion of infants weighing 3,500 g or more or birth weight ≥90th percentile. CONCLUSIONS: GCT is not superior for predicting infants weighing 3,500 g or more and birth weight ≥90th percentile, as compared with RBG.

Random Blood Glucose Concentrations and their Association with Body Mass Index in Indian School Children.

OBJECTIVE AND AIMS: Overweight/obese children are at risk of developing type 2 diabetes mellitus. Random glucose elevations provide early warning signs of glycemic dysregulation. To assess random blood glucose (RBG) concentrations and risk factors associated with prediabetes in children aged 3-18 years from six Indian regions. METHOD: Multicenter, cross sectional, observational school-based study; multi-stage stratified random sampling was carried out. Height and weight measured; body mass index (BMI) was computed. RBG measured using a glucometer. National sample survey was used for dietary patterns. Data were analyzed using SPSS 25.0 for Windows. SETTING: Study centers were from Maharashtra, Gujarat, Chhattisgarh, Assam, Tamil Nadu and Punjab from 40 selected schools. PARTICIPANT: Children aged 3-18 years were measured. RESULTS: Data on 14339 subjects (7413 boys) were analyzed. Prevalence of obesity was 5.8% and overweight-10.6%. Overall, 1% had low (<3 mmol/L), 93.7% in reference range (3.9-7.2 mmol/L) and 5.3% had elevated RBG (>7.2 mmol/L). With increasing mean BMI, there was increase in RBG concentrations. Children from Tamil Nadu were more likely to have RBG outside reference range compared to other regions (P < 0.05). Assam and Punjab had highest prevalence of RBG and BMI within reference range. Energy intake partly explained regional variations. Multivariate analysis showed male gender, urban residency, age >10 yrs (girls) and 13 yrs (boys), and overweight or obesity were predictive of prediabetes. CONCLUSION: Increased prevalence of overweight, obesity and prediabetes in Indian children are a matter of concern. Regional differences suggest that strategies to prevent obesity and combat perturbations in blood sugar may have to be customized.

The Influence of Oral Multivitamins Supplementation on Selected Oxidative Stress Parameters and Lipid Profiles among Sudanese Patients with Type-2 Diabetes.

AIM: The objective of the current study was to assess the influence of oral multivitamins supplementation on some oxidative stress parameters (serum Vitamin A, C, E, Zinc, Malondialdehyde (MDA)) and lipid profile among Sudanese patients with type- 2 diabetes mellitus (T2DM). MATERIAL AND METHOD: Three hundred Sudanese patients with T2DM and Hundred healthy subjects (control group) were enrolled in this cross-sectional study. Blood was collected after overnight fasting for 10-12 hrs. Fasting plasma glucose (FBG), lipid profiles, Glycosylated haemoglobin (HbA1c%), Serum zinc, Malondialdehyde (MDA), Vitamins A, E, and C levels were measured using standardised laboratory techniques. Data was collected with the help of a structured questionnaire and direct interview. RESULTS: Biochemical parameters of the study population were shown a highly significant difference (P value < 0.05), between the means of serum vitamin A, C, E, Zinc, MDA, HbA1c, triglycerides, HDL, FBG, total cholesterol and LDL. Significant differences in serum vitamin A, C, E, Zinc, MDA, triglycerides, HDL and FBG between people with diabetes who used multivitamins and diabetics who did not use it (P-value < 0.05). CONCLUSION: The study observed a significant increase in serum levels of vitamin A, C & E and other biomarkers parameters in patients with T2DM who take oral multivitamins supplements; such improvement may lead to minimising the diabetic complications. Further studies are needed to explore the possible therapeutic role of multivitamins supplements for T2DM patients.

Cut-off Value of Random Blood Glucose among Asian Indians for Preliminary Screening of Persons with Prediabetes and Undetected Type 2 Diabetes Defined by the Glycosylated Haemoglobin Criteria.

AIM: The increased morbidity and mortality due to type 2 diabetes can be partly due to its delayed diagnosis. In developing countries, the cost and unavailability of conventional screening methods can be a setback. Use of random blood glucose (RBG) may be beneficial in testing large numbers at a low cost and in a short time in identifying persons at risk of developing diabetes. In this analysis, we aim to derive the values of RBG corresponding to the cut-off values of glycosylated hemoglobin (HbA1c) used to define prediabetes and diabetes. METHODS: Based on their risk profile of developing diabetes, a total of 2835 individuals were screened for a large diabetes prevention study. They were subjected to HbA1c testing to diagnose prediabetes and diabetes. Random capillary blood glucose was also performed. Correlation of RBG with HbA1c was computed using multiple linear regression equation. The optimal cut-off value for RBG corresponding to HbA1c value of 5.7% (39 mmol/mol), and ≥ 6.5% (48 mmol/mol) were computed using the receiver operating curve (ROC). Diagnostic accuracy was assessed from the area under the curve (AUC) and by using the Youden's index. RESULTS: RBG showed significant correlation with HbA1c (r=0.40, p<0.0001). Using the ROC analysis, a RBG cut-off value of 140.5 mg/dl (7.8 mmol/L) corresponding to an HbA1c value of 6.5% (48mmol/mol) was derived. A cut-off value could not be derived for HbA1c of 5.7% (39 mmol/mol) since the specificity and sensitivity for identifying prediabetes were low. CONCLUSION: Use of a capillary RBG value was found to be a simple procedure. The derived RBG cut-off value will aid in identifying people with undiagnosed diabetes. This preliminary screening will reduce the number to undergo more cumbersome and invasive diagnostic testing.

The prognostic impact of hyperglycemia on clinical outcomes of acute heart failure: Insights from the heart function assessment registry trial in Saudi Arabia.

BACKGROUND: The prognostic impact of hyperglycemia (HG) in acute heart failure (AHF) is controversial. Our aim is to examine the impact of HG on short- and long-term survival in AHF patients. METHODS: Data from the Heart Function Assessment Registry Trial in Saudi Arabia (HEARTS) for patients who had available random blood sugar (RBS) were analyzed. The enrollment period was from October 2009 to December 2010. Comparisons were performed according to the RBS levels on admission as either <11.1 mmol/L or ≥11.1 mmol/L. Primary outcomes were hospital adverse events and short- and long-term mortality rates. RESULTS: A total of 2511 patients were analyzed. Of those, 728 (29%) had HG. Compared to non-HG patients, hyperglycemics had higher rates of hospital, 30-day, and 1-year mortality rates (8.8% vs. 5.6%; p = 0.003, 10.4% vs. 7.2%; p = 0.007, and 21.8% vs. 18.4%; p = 0.04, respectively). There were no differences between the two groups in 2- or 3-year mortality rates. After adjustment for relevant confounders, HG remained an independent predictor for hospital and 30-day mortality [odds ratio (OR) = 1.6; 95% confidence interval (CI) 1.07-2.42; p = 0.021, and OR = 1.55; 95% CI 1.07-2.25; p = 0.02, respectively]. CONCLUSION: HG on admission is independently associated with hospital and short-term mortality in AHF patients. Future research should focus on examining the impact of tight glycemic control on outcomes of AHF patients.

Anti diabetic property of aqueous extract of Stevia rebaudiana Bertoni leaves in Streptozotocin-induced diabetes in albino rats.

BACKGROUND: Stevia (Stevia rebaudiana) natural, non-caloric sugar substitute is rich source of pharmacologically important glycoside stevioside that is linked to the pathology and complications of diabetes. METHODS: The current research was carried out to explore the anti-diabetic effect of aqueous extract of Stevia rebaudiana leaves in albino rats. For this purpose, diabetes was induced by administration of streptozotocin (40 mg/kg body weight, intraperitoneally). The diabetic rats were administered with aqueous stevia extract at different dose levels (200, 300, 400 and 500 ppm/kg b.w) for 8 weeks; the control rats were fed basal diet during this period. RESULTS: Stevia aqueous extract improved caloric management and weight control by decreasing the feed intake and body weight gain. Furthermore, intake of stevia extract resulted in significant (P < 0.05) decrease in the random blood glucose level (- 73.24%) and fasting blood glucose (- 66.09%) and glycosylated (HbA1c) hemoglobin (5.32%) while insulin (17.82 µIU/mL) and liver glycogen (45.02 mg/g) levels significantly improved in the diabetic rats, compared with the diabetic and non-diabetic control rats after 8 weeks study period. CONCLUSIONS: It is concluded that aqueous extact of stevia has anti-diabetic effects in albino rats, and therefore could be promising nutraceutical therapy for the management of diabetes and its associated complications.

Propensity score study of the relationship between random blood glucose level and clinical outcomes of elderly patients with community-acquired pneumonia / 中国综合临床

Objective To investigate the correlation between admission hyperglycemia and clinical prognosis in elderly patients with community-acquired pneumonia.Methods Based on the electrical medical record (EMR),information of the patients with pneumonia was retrospectively collected and the necessary data were prepared and arranged.Based on clinical outcomes,demographic characteristics and clinical indicators were compared between groups in order to screen potential variables affecting clinical outcomes.Then,the random blood glucose level 8.6 mmol/L was considered to be the cutoff point for grouping patients,with clinical outcomes as outcome variables,random blood glucose levels as grouping variables,propensity score value analysis method was applied along with the ratio of 1:1 nearest neighbor matching method to generate paired samples in order to assess the impact of blood glucose level on mortality rate;With hospitalization time serving as time variable,survive analysis method was used to analyze COX proportional model.Results Five hundred and fifty-eight patients were enrolled in the analysis,197 patients of which were recorded dead during hospitalization (the dead group).After the correction of demographic characteristics,past medical history and blood test indexes,white blood cells,C reactive protein,random blood glucose at admission and triglyceride levels were regarded as potential factors for the deaths of patients (P<0.05).However,the propensity score analysis method suggested that there was no significant difference between the blood glucose levels and mortality.The survival analysis showed that the mortality in the high blood glucose group was higher than that in the normal blood glucose group (HR=1.68,95%CI(1.22,2.31)).Conclusion Admission hyperglycemia is an important indicator of adverse prognosis in elderly patients with pneumonia.It may be of significance for screening and identifying high-risk patients.

Effect of mobile reminders on screening yield during opportunistic screening for type 2 diabetes mellitus in a primary health care setting: A randomized trial.

Objective. We wanted to study whether mobile reminders increased follow-up for definitive tests resulting in higher screening yield during opportunistic screening for diabetes. Methods. This was a facility-based parallel randomized controlled trial during routine outpatient department hours in a primary health care setting in Puducherry, India (2014). We offered random blood glucose testing to non-pregnant non-diabetes adults with age >30 years (667 total, 390 consented); eligible outpatients (random blood glucose ≥ 6.1 mmol/l, n = 268) were requested to follow-up for definitive tests (fasting and postprandial blood glucose). Eligible outpatients either received (intervention arm, n = 133) or did not receive mobile reminder (control arm, n = 135) to follow-up for definitive tests. We measured capillary blood glucose using a glucometer to make epidemiological diagnosis of diabetes. The trial was registered with Clinical Trial Registry of India (CTRI/2014/10/005138). Results. 85.7% of outpatients in intervention arm returned for definitive test when compared to 53.3% in control arm [Relative Risk = 1.61, (0.95 Confidence Interval - 1.35, 1.91)]. Screening yield in intervention and control arm was 18.6% and 10.2% respectively. Etiologic fraction was 45.2% and number needed to screen was 11.9. Conclusion. In countries like India, which is emerging as the diabetes capital of the world, considering the wide prevalent use of mobile phones, and real life resource limited settings in which this study was carried out, mobile reminders during opportunistic screening in primary health care setting improve screening yield of diabetes.

Random blood glucose may be used to assess long-term glycaemic control among patients with type 2 diabetes mellitus in a rural African clinical setting.

OBJECTIVES: To investigate the diagnostic accuracy of random blood glucose (RBG) on good glycaemic control among patients with diabetes mellitus (DM) in a rural African setting. METHODS: Cross-sectional study at St. Francis' Hospital in eastern Zambia. RBG and HbA1c were measured during one clinical review only. Other information obtained was age, sex, body mass index, waist circumference, blood pressure, urine albumin-creatinine ratio, duration since diagnosis and medication. RESULTS: One hundred and one patients with DM (type 1 DM = 23, type 2 DM = 78) were included. Spearman's rank correlation coefficient revealed a significant correlation between RBG and HbA1c among the patients with type 2 DM (r = 0.73, P < 0.001) but not patients with type 1 DM (r = 0.17, P = 0.44). Furthermore, in a multivariate linear regression model (R(2) = 0.71) RBG (per mmol/l increment) (B = 0.28, 95% CI:0.24-0.32, P < 0.001) was significantly associated with HbA1c among the patients with type 2 DM. Based on ROC analysis (AUC = 0.80, SE = 0.05), RBG ≤7.5 mmol/l was determined as the optimal cut-off value for good glycaemic control (HbA1c <7.0% [53 mmol/mol]) among patients with type 2 DM (sensitivity = 76.7%; specificity = 70.8%; positive predictive value = 62.2%; negative predictive value = 82.9%). CONCLUSIONS: Random blood glucose could possibly be used to assess glycaemic control among patients with type 2 DM in rural settings of sub-Saharan Africa.
