Heterogeneity in patterns of progression of chronic kidney disease.

BACKGROUND: Progression of kidney disease is a deceptively simple word for a complex bio-clinical process, evidenced by the number of definitions in the literature. This has led to confusion and differences in interpretation of studies. METHODS: We describe different patterns of progression, the performance of different definitions of progression and factors associated with chronic kidney disease (CKD) progression in a public renal service in Australia, in a study of patients enrolled in the CKD.QLD Registry with a minimum of 2 years' follow up. RESULTS: Nine patterns of changing estimated glomerular filtration rate (eGFR) over two consecutive 12-month periods were identified. Most common was a stable eGFR over 2 years (30%), and the least was a sustainable improvement of eGFR over both periods (2.1%). There was a lack of congruence between the several definitions of progression of CKD evaluated. More people progressed using the definition of decline of eGFR of >5 mL/min/1.73 m2 /year (year 1 = 30.2%, year 2 = 20.7%) and the least using development of end-stage renal disease (year 1 = 5.4%, year 2 = 9.9%). Age (40-59, ≥80 years), degree of proteinuria at baseline (nephrotic range) and CKD aetiology (renal vascular disease, diabetic nephropathy) were significantly associated with eGFR decline over 2 years. CONCLUSIONS: This is one of the first demonstrations of the great variations among and within individuals in the progression of CKD over even a period as short as 2 years. Findings suggest considerable potential for renal function recovery and stability while demonstrating the importance of using identical definitions for comparisons across datasets from different sources.

Osteonecrosis of the Jaw among Patients Receiving Antiresorptive Medication: A 4-year Retrospective Study at a Tertiary Cancer Center, Kerala, India.

PURPOSE: Osteonecrosis of the jaw (ONJ) is a rare but complicated side effect of antiresorptive medications. The aim of the study is to evaluate the dental and drug-related factors related to ONJ among patients on these drugs at a tertiary cancer center, India. METHODOLOGY: A retrospective record review of patients who received antiresorptive medication at our center from 2011 to 2014 was done. The demographic factors, type, dosage, and duration of the medication and dental history were collected, and the data were entered an analyzed using Epidata software. RESULTS: A higher incidence of ONJ (8.1%) was noted in our sample (n = 183). Dental intervention after zoledronic acid (ZA) administration showed a statistical significance (P < 0.001). No significance (P value) was noted with respect to sex (0.78), age (0.28), median duration (0.9), and median dosage (0.9) of ZA. CONCLUSION: Oro-dental screening and dental monitoring shall reduce the incidence of ONJ. Within the limitations of our study, no significant relation could be pointed toward the dosage and duration of the drug and development of ONJ.

Use of Complementary and Alternative Medicines (CAMs) among type 2 diabetes patients in Sri Lanka: a cross sectional survey.

BACKGROUND: The incidence of chronic illnesses has increased worldwide. Diabetes is one such illness and 80% of the diabetic population lives in the developing world. There is a rapidly growing trend towards the use of Complementary and Alternative Medical practices in Diabetes. Sri Lanka is a developing Asian nation with a rich culture of Ayurvedic and native medical culture. The objective of this study was to find the prevalence of use of CAMs in a diabetic population attending a large multiethnic diabetes facility in a University unit and to assess whether there is an increase in the incidence of hypoglycaemic episodes among users of CAMs. METHODS: A cross sectional study was performed at Teaching Hospital Peradeniya between April and August 2012. Following verbal consent, 254 type 2 adult diabetic patients attending the diabetes facility were interviewed regarding the use of CAM and hypoglycaemia using an interviewer-administered questionnaire. RESULTS: Of the 252 valid results, 192 patients (76%) admitted to the use of a CAM to reduce blood glucose. Bitter gourd, ivy gourd and crepe ginger were used by 128, 113 and 92 individuals. While 19% used a single agent, 34%, 21% and 2.4% used 2,3 and more than 3 agents. The incidence of hypoglycaemia in CAM users was 21% and 16.6% in non-users. The difference was statistically not significant. (p = 0.57) Ingestion of Costus speciosus (Crepe ginger) was associated with higher incidence of hypoglycaemia (P = 0.01).Female gender was significantly associated with CAM use (p = 0.01), while the age, duration of diabetes, presence of co-morbidities and complications of diabetes failed to show a significant association. CONCLUSION: Sri Lanka has a very high use of herbal supplementation in type 2 diabetes patients. Although the overall incidence of hypoglycaemia is not increased among CAM users, crepe ginger is associated with significant hypoglycaemia and warrants further research.

A direct access to bioactive fused N-heterocyclic acetic acid derivatives.

A Cu-catalyzed new sequence involving the Ullmann type intermolecular C-C followed by an intramolecular C-N coupling and then intramolecular aza-Michael type addition (and oxidation) in a single pot afforded various fused N-heterocyclic acetic acid derivatives as inhibitors of PDE4.

Patterns of multisite pain and associations with risk factors.

To explore definitions for multisite pain, and compare associations with risk factors for different patterns of musculoskeletal pain, we analysed cross-sectional data from the Cultural and Psychosocial Influences on Disability (CUPID) study. The study sample comprised 12,410 adults aged 20-59 years from 47 occupational groups in 18 countries. A standardised questionnaire was used to collect information about pain in the past month at each of 10 anatomical sites, and about potential risk factors. Associations with pain outcomes were assessed by Poisson regression, and characterised by prevalence rate ratios (PRRs). Extensive pain, affecting 6-10 anatomical sites, was reported much more frequently than would be expected if the occurrence of pain at each site were independent (674 participants vs 41.9 expected). In comparison with pain involving only 1-3 sites, it showed much stronger associations (relative to no pain) with risk factors such as female sex (PRR 1.6 vs 1.1), older age (PRR 2.6 vs 1.1), somatising tendency (PRR 4.6 vs 1.3), and exposure to multiple physically stressing occupational activities (PRR 5.0 vs 1.4). After adjustment for number of sites with pain, these risk factors showed no additional association with a distribution of pain that was widespread according to the frequently used American College of Rheumatology criteria. Our analysis supports the classification of pain at multiple anatomical sites simply by the number of sites affected, and suggests that extensive pain differs importantly in its associations with risk factors from pain that is limited to only a small number of anatomical sites.

Growth parameters at birth of babies born in Gampaha district, Sri Lanka and factors influencing them

Background: Growth parameters at birth are important for clinical decision‑making.In Sri Lanka, the data from the World Health Organization (WHO) Multicentre GrowthReference Study (MGRS) are used to interpret these measurements.Materials and Methods: A descriptive cross‑sectional study was conductedbetween September and October 2010 in hospitals of Gampaha district, Sri Lanka.The weight, length and head circumference of all normal‑term babies born inthe Gampaha district during this period were measured within 8 h of birth usingstandard techniques. Measurements were taken by medical graduates trained andsupervised by a consultant paediatrician. Socio‑demographic data were obtainedusing an interviewer‑administered questionnaire.Results: Of the 2215 babies recruited, 1127 were males. The mean birth weight,mean length and mean head circumference at birth were 2.92 kg, 49.1 and33.6 cm, respectively. Boys weighed and measured more than girls in all parameters,but the differences were not statistically significant. Growth parameters of babiesincluded in this study deviated from that in the MGRS data. Mean values of MGRSdata were between 75th and 90th centiles of this study population. Birth order,family income and maternal education were significantly (P < 0.01) associated withgrowth parameters. Contrary to common belief, growth parameters continued toincrease progressively up to 41 weeks. Maternal age less than 20 years or morethan 35 years was negatively associated with birth weight (P < 0.01).Conclusions: Growth parameters of new‑born babies deviated significantly from thevalues of the MGRS data. Growth characteristics of one population may not be applicableto another population due to variations in maternal, genetic and socio‑economic factors.Using growth charts not applicable to a population will result in wrong interpretations
