Hepatoprotective effect of Ziziphus oxyphylla Edgew in paracetamol-induced hepatotoxic rat model.

Ziziphus oxyphylla Edgew (Z. oxyphylla) is a small shrub to a medium sized tree. The aim of the present study was to evaluate the hepatoprotective activity of Z. oxyphylla in paracetamol-induced hepatotoxic rat model. Silymarin was used as a standard drug. Methanol extract was found to be the most potent in in-vitro antioxidant studies. The methanol extract of Z. oxyphylla was administered to experimental animals. The hepatoprotective effect of extract was evaluated by measuring liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Treatment with the paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzymes. Pre-treatment with Z. oxyphylla caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes levels. It is concluded that the methanol extract of Z. oxyphylla possesses hepatoprotective activity that might be due to quercetin and kaempferol glycosides present in the plant extract. Further studies are required to elucidate the exact mechanism of action of these isolated flavonoid glycosides.

Patient characteristics associated with hospitalisations for ambulatory care sensitive conditions in Victoria, Australia.

BACKGROUND: Ambulatory Care Sensitive Conditions (ACSCs) are those for which hospitalisation is thought to be avoidable with the application of preventive care and early disease management, usually delivered in a primary care setting. ACSCs are used extensively as indicators of accessibility and effectiveness of primary health care. We examined the association between patient characteristics and hospitalisation for ACSCs in the adult and paediatric population in Victoria, Australia, 2003/04. METHODS: Hospital admissions data were merged with two area-level socioeconomic indexes: Index of Socio-Economic Disadvantage (IRSED) and Accessibility/Remoteness Index of Australia (ARIA). Univariate and multiple logistic regressions were performed for both adult (age 18+ years) and paediatric (age <18 years) groups, reporting odds ratios (OR) and 95% confidence intervals (CI) for a number of predictors of ACSCs admissions compared to non-ACSCs admissions. RESULTS: Predictors were much more strongly associated with ACSCs admissions compared to non-ACSCs admissions in the adult group than for the paediatric group with the exception of rurality. Significant adjusted ORs in the adult group were 1.06, 1.15, 1.13, 1.06 and 1.11 for sex, rurality, age, IRSED and ARIA variables, and 1.34, 1.04 and 1.09 in the paediatric group for rurality, IRSED and ARIA, respectively. CONCLUSIONS: Disadvantaged paediatric and adult population experience more need of hospital care for ACSCs. Access barriers to primary care are plausible causes for the observed disparities. Understanding the characteristics of individuals experiencing access barriers to primary care will be useful for developing targeted interventions meeting the unique ambulatory needs of the population.

Role of Platelet-Rich Plasma in the Treatment of Adhesive Capsulitis: A Prospective Cohort Study.

Background A glenohumeral (GH) joint disease, such as adhesive capsulitis, causes the shoulder capsule's fibrosis and adhesion to restrict mobility. Collagen and growth factors can be produced by platelet-rich plasma (PRP), which promotes stem cells and, as a result, improves the healing process. This study was done to determine the role of PRP injection in the treatment of adhesive capsulitis in terms of improvement in pain. Methodology This prospective cohort study was conducted at the Department of Orthopedics, Mayo Hospital, Lahore, Pakistan, from February 2022 to July 2022. A total of 305 patients were enrolled through the outpatient department. Basic demographic and clinical details, including the visual analog scale (VAS) pain score, were noted. First, 20 ml of the patient's blood was drawn from the superficial saphenous vein by double syringe. After processing, the PRP was collected and injected in the subacromial bursa and intra-articular space adopting the anatomical approach. Then, the process was repeated at weekly intervals for four weeks. In this phase, PRP was injected only in the joint. The pain was assessed before and after six weeks of treatment and improvement in pain as per VAS was noted. Results In a total of 305 cases, the mean age was 60.47±11.55 years. There were 164 (53.8%) male and 141 (46.2%) female cases. The mean pain VAS scores before and after treatment were 6.56±1.79 and 2.42±1.71, respectively, and the mean reduction in pain after treatment was 64.57±19.40%. In 267 (87.5%) cases, an improvement of ≥ 50% was observed while 38 (12.5%) cases had an improvement of <50%. Conclusion The PRP can be used for the treatment of adhesive capsulitis to reduce pain. This non-operative method of treatment may help reduce the hospital burden of patients suffering from adhesive capsulitis.

Patient educational level and use of newly marketed drugs: a register-based study of over 600,000 older people.

OBJECTIVE: To examine the association between educational level and the use of newly marketed drugs (NMD) among elderly persons. METHODS: We conducted a register-based, retrospective, cross-sectional study of 626,258 people aged 75-89 years who filled at least one drug prescription from August to October 2005 and who, consequently, were registered in the Swedish Prescribed Drug Register (SPDR). Data from the SPDR were record-linked to the Swedish National Inpatient Register and the Education Register. Newly marketed drugs were defined as new chemical entities that had been approved in Sweden between 2000 and 2004. RESULTS: Overall, NMD were prescribed to 7.3% of the study population. The use of NMD increased with increasing educational level (6.9% for the lowest educated elderly and 8.1% for the highest educated elderly), and education was associated with NMD [odds ratio (OR) 0.82; 95% confidence interval (CI)] 0.80-0.88 for <9 compared with > or =13 years of education) after adjustment for age, sex, type of residential area and number of dispensed drugs. Decreasing educational level was associated with a lower probability of using most of the NMD, especially oseltamivir (adjusted OR 0.16; 95% CI 0.12-0.22 for <9 years of education compared with > or =13 years of education) and ezetimibe. CONCLUSIONS: This study suggests that education-related inequalities in NMD use may exist even in a healthcare system that claims to ensure a high degree of equity. Future research is required to explain why educational level influences the selection of new drugs and whether it has any impact on health outcomes.

Prevalence and factors associated with polypharmacy in Victorian adults with intellectual disability.

Although polypharmacy is a medication safety concern leading to increased risk of non-adherence, adverse drug reaction and drug-drug interactions, polypharmacy and associated risk factors has rarely been investigated involving people with ID at a population level. The purpose of this paper is to analyze the prevalence of polypharmacy and to evaluate the role of different factors associated with polypharmacy in a state-wide representative population of adults with ID. In a population-based survey in Victoria, Australia, 897 people with ID 18 years of age or older were selected by simple random sampling. The data were collected from proxy respondents on behalf of people with ID. Polypharmacy was defined as the concomitant use of five or more medications. The data were weighted to reflect the age/sex/geographic distribution of the population. Results revealed that more than 76% of adults with ID had used prescribed medicine and about 21% were exposed to polypharmacy in the last two weeks. In both univariate and multivariate analyses, polypharmacy was significantly associated with older age, unemployment and inability to get help from family and friends if needed. After controlling for age, sex and severity of intellectual disability, polypharmacy was associated with having a blood pressure, blood cholesterol and blood glucose level check. Polypharmacy was also associated with a greater number of visits to general practitioners, fair or poor reported health status and inability to walk unaided. Subjects with epilepsy, diabetes, stroke, osteoporosis and cancer had a higher probability of polypharmacy. None of the disease inducing behaviors was associated with polypharmacy. This study highlights the need that medication should be regularly reviewed overall in ID population and particularly when polypharmacy exists.

Health and wellbeing of Victorian adults with intellectual disability compared to the general Victorian population.

Multiple measures of health and wellbeing of people with intellectual disability (ID) and the general Victorian population were compared using representative population level data. The sample consisted of adults with ID (N=897) and the general Victorian population (N=34,168) living in the state of Victoria in Australia. Proxy respondents were interviewed on behalf of people with ID, while respondents from the general Victorian population were interviewed directly. The data were weighted to reflect the age/sex/geographic distribution of the population. Results revealed that adults with ID reported higher prevalence of poor social determinants of health, behavioural risk factors, depression, diabetes, poor or fair health. A higher proportion of people with ID reported blood pressure and blood glucose checks, while a lower proportion reported cervical and breast cancer screening, compared with the general Victorian population. The survey identified areas where targeted approaches may be undertaken to improve the health outcomes of people with ID and provide an important understanding of the health and wellbeing of these Victorians.

The influence of educational level on polypharmacy and inappropriate drug use: a register-based study of more than 600,000 older people.

OBJECTIVES: To investigate whether low educational attainment is associated with polypharmacy and potential inappropriate drug use (IDU) in older people. DESIGN: Cross-sectional register-based study. SETTING: Sweden. PARTICIPANTS: Older people aged 75 to 89 who, filled at least one drug prescription between August and October 2005 and, consequently, were listed in the Swedish Prescribed Drug Register (SPDR) (N=626,258). Data were obtained from the SPDR, the inpatient register, and the education register. MEASUREMENTS: The main outcome measures were polypharmacy (concurrent use of > or =5 drugs), excessive polypharmacy (concurrent use of > or =10 drugs), and potential IDU. Four quality indicators developed by the Swedish National Board of Health and Welfare were used for the assessment of potential IDU: concurrent use of three or more psychotropic drugs, prescription of long-acting benzodiazepines, prescription of anticholinergics, and at least one clinically relevant potential drug-drug interaction (DDI). Comorbidity was measured using the Charlson Comorbidity Index. RESULTS: Subjects with low education had a higher probability of polypharmacy (odds ratio (OR)=1.11, 95% confidence interval (CI)=1.10-1.12), excessive polypharmacy (OR=1.15, 95% CI=1.13-1.17), and potential IDU (OR=1.09, 95% CI=1.07-1.17), after adjustment for age, sex, comorbidity, and type of residential area (urban or rural). Decreasing educational attainment was associated with a higher probability of using three or more psychotropic drugs and potential DDIs, whereas the opposite association was observed for anticholinergic drugs. Long-acting benzodiazepines showed no association. Elderly women with low education were slightly more likely to have polypharmacy, excessive polypharmacy, and potential IDU than men with low education. Overall, the ORs were modest and statistically significant because of the large sample size. CONCLUSION: Low educational attainment was associated with a greater likelihood of poypharmacy, excessive polypharmacy, and potential IDU in elderly Swedish persons, even after controlling for age, sex, place of residence, and comorbidity. Women with low education had slightly higher likelihood of receiving polypharmacy and potential IDU than men with low education. The recently established SPDR may be useful for continuous monitoring and for designing interventions to improve drug quality in low-educated elderly people.

Analysis of the association between polypharmacy and socioeconomic position among elderly aged > or =77 years in Sweden.

BACKGROUND: Polypharmacy is an important patient safety concern and has been associated with increased adverse drug reactions, hospitalization, and mortality in the elderly. However, few studies have analyzed the association between socioeconomic position (SEP) and the extent of drug use in older people. OBJECTIVES: The aims of this study were to investigate the prevalence of polypharmacy and the association between polypharmacy and SEP, as measured by education, occupation, and income. METHODS: For this cross-sectional study, data from a nationally representative sample (Swedish Panel Study of Living Conditions of the Oldest Old [SWEOLD] 2002) aged > or =77 years were analyzed (n = 621). Information on drug use was based on personal interviews, and polypharmacy was defined as concurrent use of > or =5 drugs. Other measurements included were age, sex, education, occupation, income, comorbidity, marital status, and living situation. The association between polypharmacy and SEP was assessed by logistic regression. RESULTS: The mean number of drugs used in the sample was 4.4; in less educated patients, 4.6; more educated, 4.0. Polypharmacy was observed in 42.2% of the elderly. Overall, antithrombotic agents (42.5%), P-blocking agents (28.3%), and high-ceiling diuretics (28.0%) were the most prevalent drugs. Low education was associated with polypharmacy (odd ratio [OR], 1.46; 95% CI, 1.02-2.07), after controlling for age and sex. However, the association between low education level and polypharmacy was not significant after adjustment for age, sex, comorbidity, marital status, and living situation (OR, 1.39; 95% CI, 0.95-2.04). Moreover, we did not observe any association between occupation or income and polypharmacy. CONCLUSIONS: The results from this study suggest that >40% of people aged > or =77 years in Sweden are exposed to polypharmacy, defined as the use of > or =5 drugs. There was a higher prevalence of polypharmacy among elderly with low education. However, after controlling for comorbidity, martial status, and living situation, polypharmacy was not related to low education. Further studies in larger populations are needed to elucidate the association between SEP and drug use.
