Medicine (Baltimore), 2018 Mar;97(12):e9847.
PMID: 29561461 DOI: 10.1097/MD.0000000000009847

BACKGROUND: Diabetes self-care activities, like, healthy diet, regular exercise, self-monitoring of blood glucose, and rational use of medicines are considered to play a vital role in establishing euglycemia. Health literacy among type 2 diabetes mellitus (T2DM) patients in Pakistan is very low, which is the most likely cause for poor clinical outcomes. This study is designed to investigate the impact of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among T2DM patients in Pakistan.

METHODS: In this randomized controlled trail, effectiveness of a 6-month pharmacist-led educational intervention will be examined on glycemic control, diabetes self-care activities and disease knowledge of 80 adult T2DM patients (age >30 years) with poorly controlled T2DM (HbA1c> 7%), after randomizing them into intervention and control groups, at diabetes care clinic of Capital Hospital Islamabad, Pakistan.

RESULTS: The primary outcome is change in patients' HbA1c, whereas, changes in self-care activities and patients' disease knowledge are the secondary outcomes. After baseline assessment of their self-care activities and disease knowledge by using validated Urdu versions of Diabetes Self-management Questionnaire (DSMQ) and Diabetes Knowledge Questionnaire (DKQ), respectively, interventional group patients will be supplemented with a face-to-face pharmacist-led educational intervention, whereas, the control group will receive usual care. Intervention arm patients will be educated successively at their first follow-up visit (12th week) and telephonically after every 4 weeks. All assessments will be made at baseline and end of trail for both intervention and control groups. Multivariate general linear model will be applied to analyze the effects of the intervention.

CONCLUSION: Glycemic control in T2DM patients requires optimum self-care activities. This study is an attempt to improve self-care behaviors among poorly controlled T2DM patients who are at higher risk of diabetes-associated late complications.

PMID: 37484541 DOI: 10.1016/j.jsps.2023.06.004

BACKGROUND & OBJECTIVES: This study aimed to create a controlled delivery system for Tapentadol Hydrochloride by developing interpenetrating networks (IPNs) of Natrosol-Pectin copolymerized with Acrylic Acid and Methylene bisacrylamide, and to analyze the effects of various ingredients on the physical and chemical characteristics of the IPNs.
METHODS: Novel Tapentadol Hydrochloride-loaded Natrosol-Pectin based IPNs were formulated by using the free radical polymerization technique. Co-polymerization of Acrylic Acid (AA) with Natrosol and Pectin was performed by using Methylene bisacrylamide (MBA). Ammonium persulfate (APS) was used as the initiator of crosslinking process. The impact of ingredients i.e. Natrosol, Pectin, MBA, and Acrylic Acid on the gel fraction, porosity, swelling (%), drug loading, and drug release was investigated. FTIR, DSC, TGA, SEM and EDX studies were conducted to confirm the grafting of polymers and to evaluate the thermal stability and surface morphology of the developed IPNs.
RESULTS: Swelling studies exhibited an increase in swelling percentage from 84.27 to 91.17% upon increasing polymer (Natrosol and Pectin) contents. An increase in MBA contents resulted in a decrease in swelling from 85 to 67.63%. Moreover, the swelling was also observed to increase with higher AA contents. Significant drug release was noted at higher pH instead of gastric pH value. Oral toxicological studies revealed the nontoxic and biocompatible nature of Natrosol-Pectin IPNs.
INTERPRETATION & CONCLUSION: The developed IPNs were found to be an excellent system for the controlled delivery of Tapentadol Hydrochloride.

Patient Prefer Adherence, 2018;12:2377-2385.
PMID: 30519003 DOI: 10.2147/PPA.S177314

Objective: Association of various self-care activities on glycemic control of people with diabetes (PWD) in Pakistan is yet to be explored. The current study aimed to evaluate the association of various diabetes-related self-care activities with glycated hemoglobin (HbA1c) levels and to examine the predictive relationship of patients' demographic variables with their self-care activities.

Patients and methods: A cross-sectional study was conducted on adult PWD (N=218) who were diagnosed with type 2 diabetes mellitus of at least 1 year duration. Self-care activities were examined by using the Urdu version of Diabetes Self-management Questionnaire. Linear regression analysis was conducted to examine the significant predictors for diabetes-related self-care activities and glycemic control.

Results: Mean age of the patients was 50.77±13.3 years. Poor glycemic control (HbA1c $7%) was observed in majority of the patients (83%). Linear regression analysis revealed that glucose management (β=-0.44; 95% CI -0.438, -0.209; P<0.001) was the strongest predictor for low levels of patients' HbA1c, followed by dietary control (β=-0.19; 95% CI -0.248, -0.018; P=0.024) and physical activity (β=-0.17; 95% CI -0.165, -0.023; P=0.010), respectively. Linear regression analysis showed that use of oral hypoglycemic agents only (β=-0.218; 95% CI -0.956, -0.200; P=0.003) and higher education level (β=0.204; 95% CI 0.138, 0.777; P=0.005) were significant predictors for higher scores of patients' self-care activities.

Conclusion: The findings support that PWD having better self-reported self-care activities achieve better glycemic control. Patients' self-care activities should be monitored on a regular basis, especially for those who are at risk of poor glycemic control.

BACKGROUND AND AIMS: Restless legs syndromes (RLS) are intrinsic sleeping disorder and its prevalence rate is 10-15% in general population but it is observed that prevalence rate is different in diabetes patients. Current study aims to find prevalence and determinants of RLS in people living with type 2 diabetes mellitus in Pakistan.
METHOD: A multicenter cross-sectional observational study was conducted in 388 diabetes patients attending daily diabetes clinics and teaching hospitals in Pakistan's twin city between August 2019 and February 2020. The chi-square test and linear regression were used to detect RLS-related factors in type 2 diabetes mellitus.
RESULTS: The prevalence of RLS found was; 3.1% patients with diabetes were suffering from very severe RLS, 23.5% from severe RLS, 34% from moderate RLS, 21.1% from mild RLS and 18.3% from non-RLS. Gender, age, education, blood glucose fasting (BSF), blood glucose random (BSR) and HBA1c were found to be significant predictors of RLS in patients with diabetes.
CONCLUSION: Policy makers can develop local interventions to curb the growing RLS prevalence by keeping in control the risk factors of RLS in people living with type 2 diabetes.
