To compare blood pressure (BP), intraocular pressure (IOP), ophthalmic artery flow (OAF) velocity, retinal nerve fiber layer (RNFL) thickness, and visual fields in newly diagnosed hypertension (HT) patients (before treatment), chronic HT (on antihypertensive medications >5 years) and normotensives. A prospective, cross-sectional study at a tertiary care centre in India. Three groups of 45 patients each: group 1 - early HT, group 2 - chronic HT, and Group 3 - normotensives, underwent evaluation of BP, IOP by Goldmann applanation tonometry (GAT), OAF velocity by transcranial doppler (TCD), RNFL analysis by spectral-domain optical coherence tomography (SD-OCT), and visual fields. The BP was highest in early HT > chronic HT > normotensives (p < 0.001). The IOP of early HT, chronic HT, and normotensives were 15.87 ± 2.19 mmHg, 13.47 ± 1.92 mmHg, and 15.67 ± SD 1.75 mmHg (p < 0.001). The OAF velocity [peak systolic velocity (PSV), end-diastolic velocity (EDV) in cm/sec] was lowest in chronic HT (30.80 ± 7.05, 8.58 ± 1.58) < early HT (35.47 ± 5.34, 10.02 ± 1.74) < normotensives (36.29 ± 4.43, 10.44 ± 2.29), (p < 0.001). The average RNFL thickness was significantly lower in chronic HT (p = 0.022). The PSV, EDV, and MFV showed significant correlation with IOP (r = 0.247, p = 0.004; r = 0.206, p = 0.016; r = 0.266, p = 0.002) and average RNFL thickness (r = 0.309, p= <0.001; r = 0.277, p = 0.001; r = 0.341, p < 0.001) Patients with chronic HT demonstrated the lowest retrobulbar flows, IOP and lower RNFL measurements. Lower ocular perfusion may be associated with lower IOP and may be a risk factor for end-organ damage (RNFL) independent of IOP. [ABSTRACT FROM AUTHOR]

Context: Combating human immunodeficiency virus/acquired immunodeficiency syndrome epidemic has been possible due to advances in prevention strategies and Antiretroviral therapy (ART). Optimal adherence to ART is a major factor in achieving the desired immunological, virological, and patient well‑being outcomes. Several socio‑demographic, patient, treatment, and health‑care system‑related factors influence nonadherent behavior to ART. Aims: This study was planned to assess (1) ART adherence level, (2) factors and reasons associated with nonadherence, and (3) impact of suboptimal adherence on treatment outcomes. Settings and Design: This was a cross‑sectional analytical study of 300 patients in a tertiary care hospital in Puducherry, India. Methods: Random sampling was used to collect data from patient treatment cards and a predesigned structured questionnaire. The pill count method was used to calculate adherence level. Statistical Analysis Used: Nonadherence was chosen as a dependent variable and factors affecting adherence were chosen as independent variables. Test for significance was carried out by Chi‑square test and Fisher’s exact test. Results: Optimal adherence was seen in 68.3%. Factors significantly associated with nonadherence were lower education level, high prior CD4 count, irregular follow‑up, missing doses in the past, and being late for pharmacy pill refills. Adherence was positively associated with mean increase in CD4 count over 6 months. Conclusions: In our study, the adherence rate is suboptimal which can lead to failure of ART. Nonadherence was associated with a decrease in CD4 count overtime. Most of the factors significantly affecting ART adherence were patient behavior related. These factors can be used for target intervention during reinforcement adherence counseling. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effect of reducing blood pressure (BP) by atenolol and amlodipine on (1) intraocular pressure (IOP) and (2) ophthalmic artery blood flow (OAF) velocity in new hypertensives. Methods: A prospective, observational cohort study conducted at a tertiary care center in India after IRB approval. New hypertensives treated with atenolol 25 mg or amlodipine 5 mg were divided into 2 groups of 30 patients each. BP, IOP by Goldmann applanation tonometry and OAF velocity by transcranial doppler sonography was performed before medication and post medication on day 1, 7, and 30. Results: There was a significant decrease in IOP with both drugs; the effect was greater with atenolol. Atenolol: premedication IOP - 16.06 ± 2.13 mmHg and day 30-12.46 ± 1.94 (22.4%) [P < 0.001], amlodipine: premedication IOP-15.13 ± 2.55 mmHg and day 30- 13.06 ± 2.14 (13.68%) [P < 0.001]. A decrease of 0.5 mmHg in IOP with every 10 mmHg (95% CI: 0.121-0.826, P value = 0.01) decrease in systolic BP was noted after oral atenolol. The OAF peak systolic velocity and mean flow velocity were equally reduced with both drugs (P < 0.001). The end-diastolic velocity, reduced only with atenolol (P = 0.049) but returned to baseline with amlodipine at 1 month. Conclusions: BP reduction by atenolol and amlodipine led to decreases in IOP and OAF velocity, greater with atenolol. The IOP decrease was likely due to reduced blood flow. A slight decrease in the diastolic flow of the ophthalmic artery was noted with atenolol. [ABSTRACT FROM AUTHOR]

Background: Curcumin is a naturally derived yellow polyphenolic compound from the rhizome Curcuma longa. Curcumin modulates various signalling pathways, such as Cyclooxygenase-2 (COX-2), Matrix metallopeptidases (MMPs), glutathione, protein kinase C, ATPase, nuclear Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-kb), Activator protein 1 (AP-1), P-glycoprotein 1 (P-gp), Multidrug resistance-associated proteins (MRP-1, MRP-2), Receptor tyrosine-protein kinase (ErbB2), Alpha-1-acid glycoprotein AGP), Cyclin D1 etc. Curcumin, as a free drug, has a short plasma half-life because it is rapidly metabolised in the liver. Its oral bioavailability is extremely poor, and hence Curcumin is classified as a class IV compound in the BCS system. Materials and Methods: Authors of the current study have formulated Liposomal Curcumin and conducted a Relative Oral Bioavailability Study of Liposomal Curcumin in comparison with plain Curcumin in rats. The treatment group was given Curcumin 25% I lipo at the dose of 500 mg/kg body weight and the control group was given plain Curcumin 500 mg/ kg body weight of the rats. Observations: Oral administration of Liposomal Curcumin showed rapid absorption (tmax =15 min) with Peak plasma concentration (Cmax), Area under Curve (AUC) and half-life (t1/2) of 42.3 ng/ml, 244 ng.h/ml and 5.5 h, respectively. In the control group, the Curcumin levels were below the level of quantitation (5.43 ng/ml). Conclusion: This study shows that Liposomal Curcumin has higher bioavailability as compared to the marketed formulations of Curcumin. Further extensive clinical studies are needed to prove efficacy of Liposomal Curcumin in various human applications. [ABSTRACT FROM AUTHOR]
