Effects of Clinical Pharmacology Training on Prescription Writing Skills of Interns

Introduction: The skill of appropriate prescription writing is a corner stone of treatment. Due to this fact, we designed a study for evaluating interns prescription writing skills after clinical pharmacology training. Methods: One hundred medical students of Tabriz University of medical science and Tabriz Azad medical university (TAMU) were chosen as intervention group and other one hundred medical students were selected as controls. Clinical pharmacology training was the intervention when the students were in internal medicine ward. Their prescribing skills were evaluated using a questionnaire. Results: Twenty eight percent of TUMS non- trained students and 68% of trained students were interested in pharmacology classes (P<0.001). Knowledge of pharmacology in non- trained TUMS students was 22% poor and 6% perfect, but in trained TUMS students it was 2% poor and 18 % perfect. In TUMS students, 80% and TAMU, 68% of the interns announced that clinical pharmacology training was essential (P= 0.25). Most of the interns had problems in correct dictation, dosage, dose adjustment of the drugs and only 4% of them had minor problems. In trained group, most of their problems solved. Conclusion: Pharmacology classes which are a part of educational curriculum during the fourth year of medical training is not enough for future clinical rotations. Clinical pharmacology training is essential for improving the prescription writing skills

Insights into the role of matrix metalloproteinases in precancerous conditions and in colorectal cancer

Colorectal cancer (CRC) is the third and second cancer for incidence and mortality worldwide, respectively, and is becoming prevalent in developing countries. Most CRCs derive from polyps, especially adenomatous polyps, which can gradually transform into CRC. The family of Matrix Metalloproteinases (MMPs) plays a critical role in the initiation and progression of CRC. Prominent MMPs, including MMP-1, MMP-2, MMP-7, MMP-8, MMP-9, MMP-12, MMP-13, MMP-14, and MMP-21, have been detected in CRC patients, and the expression of most of them correlates with a poor prognosis. Moreover, many studies have explored the inhibition of MMPs and targeted therapy for CRC, but there is not enough information about the role of MMPs in polyp malignancy. In this review, we discuss the role of MMPs in colorectal cancer and its pathogenesi

Atorvastatin and carnitine combination versus atorvastatin alone impacts on the lipid profile of haemodialyzed patients: A randomised clinical trial

Introduction: Dyslipidemia is one of the most common problems in hemodialysis patients and healthcare system. Some studies have suggested the use of carnitine in the treatment of dyslipidemia in hemodialysis patients. This study was carried out aiming to evaluate the effect of atorvastatin and carnitine combination versus atorvastatin alone on the lipid profile of hemodialyzed patients. Methods: In this clinical trial, 50 hemodialysis patients referred to the educational centres of Tabriz University of Medical Sciences, Tabriz, Iran, for haemodialysis were enrolled. Patients were randomly assigned into two groups. In the first group, patients were treated with carnitine (1000 mg three times daily) and atorvastatin (10-80 mg/day based on the baseline lipid profile of the patients) and in the second group, the patients were treated with atorvastatin alone for six months. The levels of triglyceride (TG), cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and haemoglobin before and after intervention were compared. The side effects of carnitine administration were also evaluated. Results: Results showed that TG, cholesterol, and LDL levels were significantly lower in the carnitine group compared to those in the other group at the end of study (P < 0.050). In addition, HDL and haemoglobin levels were significantly higher in the carnitine group in comparison to the other group (P < 0.050). No major side effects of carnitine were observed among the patients. Conclusion: The use of carnitine plus atorvastatin combination is an effective and safe method in the treatment of dyslipidemia in patients undergoing hemodialysis without imposing significant side effects

The application of gene expression profiling in predictions of occult lymph node metastasis in colorectal cancer patients

A key factor in determining the likely outcome for a patient with colorectal cancer is whether or not the tumour has metastasised to the lymph nodes-information which is also important in assessing any possibilities of lymph node resection so as to improve survival. In this review we perform a wide-range assessment of literature relating to recent developments in gene expression profiling (GEP) of the primary tumour, to determine their utility in assessing node status. A set of characteristic genes seems to be involved in the prediction of lymph node metastasis (LNM) in colorectal patients. Hence, GEP is applicable in personalised/individualised/tailored therapies and provides insights into developing novel therapeutic targets. Not only is GEP useful in prediction of LNM, but it also allows classification based on differences such as sample size, target gene expression, and examination method

Detection and Management of Common Medication Errors inInternal Medicine Wards: Impact on Medication Costs and Patient Care

Introduction: Medication errors (MEs) are a leading cause of morbidity and mortality, yet they have remained as confusing and underappreciated concept. The complex pharmacotherapy in hospitalized patients and sometimes serious clinical consequences of MEs necessitate continued report and surveillance of MEs as well as persistent pharmaceutical care for patients at medical wards. This study evaluated the frequency, types, clinical significance, and costs of MEs in internal medicine wards. Method: In this 8-month prospective and cross-sectional study, an attending clinical pharmacist, as an integral member of a health care team, visited the patients during each physician's ward round at the morning. All MEs including prescription, transcription, and administration errors were detected, recorded, and subsequently appropriate corrective interventions were proposed during these rounds. The changes in the medications' cost after implementing clinical pharmacist's interventions were compared to the calculated medications' cost, assuming that the MEs would not have been detected by clinical pharmacist and continued up to discharge time of the patients. Results: 89% of the patients experienced at least one ME during their hospitalization. A mean of 2.6 errors per patient or 0.2 errors per ordered medication occurred in this study. More than 70% of MEs happened at the prescription stage by treating physicians. The most prevalent prescription errors were inappropriate drug selection, unauthorized drugs and untreated indication. The highest MEs occurred on cardiovascular agents followed by antibiotics, and vitamins, minerals, and electrolytes. Total number of MEs showed a marked correlation with the total number of ordered medications and patients’ length of hospitalization. The net effect of clinical pharmacist’s contributions in medication therapy management was to decline medications’ costs by 33.9%. None of the MEs caused the patients harm. Conclusion: The role of clinical pharmacy services in detection, prevention and reducing the cost of MEs is of paramount importance to internal medicine wards.

Children’s and adolescents’ rising animal-source food intakes in 1990–2018 were impacted by age, region, parental education and urbanicity

Animal-source foods (ASF) provide nutrition for children and adolescents’ physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the world’s child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 15–19 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes.publishedVersio

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.8–14.4 million) incident T2D cases, representing 70.3% (68.8–71.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.0–27.1%)), excess refined rice and wheat intake (24.6% (22.3–27.2%)) and excess processed meat intake (20.3% (18.3–23.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.4–87.7%)) and Latin America and the Caribbean (81.8% (80.1–83.4%)); and lowest proportional burdens were in South Asia (55.4% (52.1–60.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally.publishedVersio
