Effect of Dosage Reduction of Hypoglycemic Multidrug Regimens on the Incidences of Acute Glycemic Complications in People With Type 2 Diabetes Who Fast During Ramadan: A Randomized Controlled Trial.

Objective: We aimed to investigate the effect of dosage reduction of four hypoglycemic multidrug regimens on the incidences of acute glycemic complications in people with type 2 diabetes who fast during Ramadan. Methods: We conducted an open-label, parallel-group, randomized controlled trial at a tertiary care center in Amman, Jordan. We recruited adults with type 2 diabetes who expressed an intention to fast during Ramadan and were adherent to one of four regimens-namely: metformin and glimepiride; metformin and vildagliptin; metformin and insulin glargine U100; or, metformin, insulin glargine U100, and human regular insulin. We randomly assigned participants in a 2:1 ratio to low- or regular-dosage therapy. The primary outcomes were the incidences of hypoglycemia and hyperglycemia during the 29 days of Ramadan 2017, and the secondary outcomes were the incidences of diabetic ketoacidosis and hyperosmolar hyperglycemic state during the same period. Results: We randomly assigned 687 participants to low-dosage therapy (n = 458) or regular-dosage therapy (n = 229) and included 678 (452 and 226, respectively) in the final analysis. The incidence of hypoglycemia was lower in the low-dosage group compared with the regular-dosage group (19 [4.2%] vs. 52 [23.0%], respectively; OR, 0.15 [95% CI, 0.08-0.26]; P < 0.001). The incidence of hyperglycemia did not differ between the low- and regular-dosage groups (319 [70.6%] vs. 154 [68.1%], respectively; OR, 1.12 [95% CI, 0.79-1.58]; P = 0.5). No participants experienced diabetic ketoacidosis or hyperosmolar hyperglycemic state. Each 1% decrease in the baseline HbA1c concentration was associated with a 19.9-fold (95% CI, 9.6-41.5; P < 0.001) increase in the odds of hypoglycemia, and each 1% increase in the baseline HbA1c concentration was associated with a 15.7-fold (95% CI, 10.0-24.6; P < 0.001) increase in the odds of hyperglycemia. Conclusion: Dosage reduction decreases the incidence of hypoglycemia without a concomitant increase in the incidences of hyperglycemia, diabetic ketoacidosis, and hyperosmolar hyperglycemic state in people with type 2 diabetes who fast during Ramadan.

Mini-mental state examination (MMSE) scores in elderly Jordanian population.

Background: The Mini-Mental State Examination (MMSE) is a simple informative and validated screening test of cognitive functions. No data of MMSE scores has been published about elderly Jordanian population. Objective: To study the MMSE scores in the elderly Jordanian population (defined as age of 50 years or more). Methods: This was a cross sectional study. A 250 healthy elderly Jordanians were interviewed and tested for their MMSE score. Their scores were analyzed and the effect of age, gender, education, marital status, diabetes mellitus (DM), hypertension (HTN), smoking, dyslipidemia, heart disease (HD), and family history of dementia (FHD) on the score was studied. Results: MMSE scores of 236 elderly subjects, aged 63±8.4 years (range 50-86 years) were analyzed. There were 111 (47%) males. There was a direct correlation between MMSE score and education level. People with a higher education (college) had the highest scores in comparison with people who are illiterates or have a high school level. The score correlated negatively with age (Pearson correlation r = -0.23, p = 0.00). Other studied variables did not correlate with score on multivariate analysis. Conclusion: Jordanians ≥50 years old with no previous brain disease scored 26.7 ± 3.2. Education was the most important determining factor of this score. the score showed also a negative correlation with age. We suggest that in this population a cut off score of 24 for those with high education beyond high school and 21 for those with up to high school education and it is not appropriate for illiterate.
