AbstractChange in diet, life style and increased life expectancy has led to the dramatic escalation in old age related complication like cognitive decline leading to dementia. Cardiovascular diseases (CVD) are huge risk factors for dementia, including Alzheimer disease (AD). Hypertension is very well known to cause cognitive impairment. Control of CVD could provide protection against dementia. Earlier, in the mouse model of AD, reserpine, an antihypertensive and antipsychotic drug could elicit improvement in the working memory in AD model mice and enhance the same in normal mice. Hence, Cognitive protection in the patients on chronic antihypertensive drug which contains reserpine was evaluated. Cognition in a cohort (in the South Indian rural population) of hypertensive patients (majority age group – 50-70 years) who have been chronically treated with a combinatorial drug, (adelphane/adelphane esidrex-Novaritis, Switzerland) consisting of reserpine and hydrazine for years was compared with controls without hypertension. The cohorts were age, sex, socio-economic, education background matched. Cognition was scored using the Tamil version of: Addenbrooke’s Cognitive Examination-III (T-ACEIII) and Tamil-Montreal Cognitive Assessment (T-MoCA) scales. The composite T-ACEIII score of control and treated groups were 53.6 and 53.2, respectively. T-MoCA scores (Control-15.1 and Treated-14.7) did not show much alteration. Further, the mean scores of the control and treated groups’ individual components of cognition in ACE, namely, Attention, Memory, Fluency, Language and visuospatial – cognitive skills also did not reveal significant difference. Thus, controlling blood pressure or hypertension with chronic antihypertensive medication like adelphane/adelphane esirdex (reserpine containing drugs) has retained normal cognition in both genders.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

Purpose. Intravitreal antivascular endothelial growth factor (anti-VEGF) therapy has been widely used for the treatment of neovascularization (NV) secondary to age-related macular degeneration (AMD). This study aimed to compare the efficacy among different subtypes of neovascular age-related macular degeneration (nAMD). Methods. PubMed, Embase, and the Cochrane Library were searched for eligible studies. We performed meta-analysis using Review Manager 5.3 and Stata/SE 12.0. Results. A total of 24 studies met our inclusion criteria and were included in the systematic review. At 3 months, the mean logarithm of the minimum angle of resolution (logMAR) improvements were −0.09, −0.18, and −0.23 for type 1, 2, and 3, respectively, while the mean macular thickness (MT) changes were −104.83, −130.76, and −196.29 μm. At 12 months, the mean changes in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters were 6.38, 8.12, and 9.37, while the MT decrease was 126.51, 126.52, and 139.85 μm, respectively. However, statistically significant difference was only found between type 1 and 3 in vision improvement, both in the short term (p=0.0002) and long term (p=0.01). Conclusions. The reactivity to VEGF inhibitors varied among different subtypes of nAMD. The efficacy of intravitreal anti-VEGF therapy in type 3 nAMD was statistically better than type 1 when considering vision improvement at 3 and 12 months. Thus, the lesion subtype is a predictor for the treatment outcome which can help guide prognosis.

Endothelial Growth Factors

Intravitreal injections of antivascular endothelial growth factors have been considered a milestone in the treatment of neovascular age-related macular degeneration (nAMD). However, the increasing incidence of AMD and the burden of visits and injections overcharge both the patient and the healthcare systems. Real-world solutions depend on treatment protocols aimed at optimizing the number of clinical visits while guaranteeing good functional outcomes. We performed a retrospective analysis of 72 eyes from 63 naïve patients diagnosed with nAMD that underwent a fixed intravitreal protocol consisting of bimonthly injections after a three-month loading dose, with either Aflibercept or Ranibizumab (no predefined criteria for treatment selection). Best corrected visual acuity (BCVA) and optical coherence tomography were analyzed at baseline and during follow-up clinical visits (months 3, 6, 12, and 18). From the included participants, 42 followed a fixed regimen with Aflibercept and 30 with Ranibizumab. At the 12-month visit, there was not a statistically significant difference in the mean change of BCVA between the two groups (p=0.121); however, the mean difference in the central retinal thickness was significantly superior in the Aflibercept group (-142.2 versus -51.5, p=0.011). The described fixed regimen seems to be efficient in the treatment of nAMD in a clinical practice setting.

The lectin-like, oxidized low-density lipoprotein (ox-LDL) receptor-1 (LOX-1)/ox-LDL system contributes to atherosclerosis and may be involved in cartilage degeneration. The purpose of this study was to determine whether the LOX-1/ox-LDL system contributes to age-related osteoarthritis (OA) in vivo, using LOX-1 knockout (LOX-1 KO) mice. Knee cartilage from 6, 12, and 18-month old (n = 10/group) C57Bl/6 wild-type (WT) and LOX-1 KO mice was evaluated by determining the Osteoarthritis Research Society International (OARSI) score of Safranin-O stained samples. The prevalence of knee OA in both mouse strains was also investigated. Expression levels of LOX-1, ox-LDL, runt-related transcription factor-2 (Runx2), type-X collagen (COL X), and matrix metalloproteinase-13 (MMP-13) in the articular chondrocytes were analyzed immunohistologically. No significant difference was observed in the mean scores of WT (2.00±0.61) and LOX-1 KO mice (2.00±0.49) at 6 months of age (P=1.00, n=10). At 12 and 18 months of age, the mean scores of LOX-1 KO mice (3.75±0.93 and 5.50±0.78) were significantly lower than those of WT mice (5.25±1.14 and 9.00±1.01; P<0.001 in both cases; n=10). The prevalence of OA in LOX-1 KO mice was lower than that in WT mice at 12 and 18 months of age (40 vs 70%, 70 vs 90%, respectively; n=10). The expression levels of Runx2, COL X, and MMP-13 in articular chondrocytes significantly decreased in LOX-1 KO, mice compared with those in WT mice. The study indicated that the LOX-1/ox-LDL system in chondrocytes plays a role in the pathogenesis of age-related knee OA, which is potentially a target for preventing OA progression.

The Difference

Prior research documented differences in fasting plasma glucose (FPG) between older and younger masters athletes at the Golden Oldies Rugby Festival (GORF). It was the purpose of our study to further investigate FPG on a larger sample. FPG data was collected on 486 participants at the Sydney World Masters Games. Of the males, 241 reported optimal FPG and 36 reported sub-optimal FPG. For females 183 reported optimal FPG and 26 reported sub-optimal FPG. Analysis was conducted utilising the age ranges implemented in past research on the GORF. The mean FPG for masters athletes below 50 years old was 5.10±1.52 mmol/L, whilst for those 50 years and above it was 5.01±1.02. The difference between the groups was not significant (t = 0.722, p = 0.471). This aligned with the finding of the GORF study that there was no significant difference in FPG between the different age ranges analysed. The sample size obtained for this investigation of FPG in masters athletes was more than double the number of participants used in previous research on the GORF. Many participants had FPG above optimal levels. Therefore, an age-related decline in pancreatic function may outweigh protective exercise benefits attained from masters sport participation.

BACKGROUND This study aimed at profiling cognitive functions in patients with age-related macular degeneration (AMD). OBJECTIVE The aim of our study was to evaluate cognitive functions in patients diagnosed with AMD METHODS This cross-sectional investigation enrolled 45 patients with AMD and 45 age- and sex-matched controls. The overall cognitive performance in AMD sufferer versus control subjects was asses using the Persian version of the Addenbrooke’s Cognitive Examination battery (ACE-R). Subjects’ sleep quality was also evaluated using the Pittsburgh Sleep Quality Index (PSQI). The mean global assessment and subscale scores were statistically compared between groups. RESULTS The mean global scores for ACE-R in AMD and control groups (80.4±12.3 and 86 ± 9.6, respectively) were found to be statistically different (p=0.018). On the other hand there was no significant difference (p=0.793) between the AMD and control groups in terms of PSQI scores (9.7±2.8 and 9.8±2.8, respectively). CONCLUSIONS AMD patients seem to have cognitively underperformed in memory and verbal fluency domains compared to the control group. Evidence on cognitive impairments in patients with AMD may possibly herald neurocognitive insufficiencies and have common pathological mechanisms with dementias.

AimTo evaluate 12-month outcome of intravitreal ziv-aflibercept (IVZ) therapy in eyes with neovascular age-related macular degeneration (nAMD) that are non-responsive to bevacizumab and ranibizumab.MethodsThis retrospective study included 16 eyes (14 patients) with nAMD who were on prior treatment with bevacizumab and ranibizumab and were treated with as-needed IVZ (1.25 mg/0.05 mL) for 12 months. The primary outcome measure was the mean change in best corrected visual acuity (BCVA) and secondary outcome measures included mean change in central macular thickness (CMT), retinal pigment epithelial detachment (RPED) heights, longest treatment free interval, presence of subretinal fluid (SRF) and intraretinal fluid (IRF) and adverse events.ResultsThere was no change in the mean logarithm of minimum angle of resolution (logMAR) BCVA at baseline and following treatment with IVZ therapy (p=0.978). The mean number of IVZ injections during 12 months was 5.9±3.3, and the mean number of antivascular endothelial growth factors (VEGFs) injections prior to switching to IVZ was 8.4±4.7. The mean treatment free interval was longer during IVZ therapy (114.4±67.1 days) compared with 76.3±54.6 days before IVZ therapy (p=0.03). Five (31.25%) eyes had visual gains of at least 0.1 logMAR, 3 (18.75%) eyes had stable BCVA (within 0.1 logMAR) and 8 (50%) eyes had BCVA decline of at least 0.1 logMAR. There was no significant difference in the mean CMT, RPED heights and presence of IRF and SRF at 12 months compared with baseline. No adverse events were noted.ConclusionIVZ increased the treatment free interval in non-responders but no significant change in visual and anatomic outcomes.

Abstract Introduction Basal angle, Boogaard’s angle, and clival angle are frequently used in diagnosing the craniometric angle malformations either on radiography or now more on MRI. But anatomic and clinical studies have used varied terms for these parameters. We aimed to look for these parameters among a normal south Indian adult population to standardize the measurements and their terminology. Materials and Methods One hundred MRI images (50 males and 50 female) were studied retrospectively. MRI images that were reported as normal by neuroradiologist were taken up for the study. Mean and the standard deviation of males and females were calculated for basal angle, Boogaard’s angle, and clival angle, separately. Unpaired t-test was used to analyze the significant difference (p < 0.05) between the genders. The intraclass coefficient correlation was used to analyze the interobserver variability. Results The mean value of basal angle in males and females are 113°and 114°, respectively. The mean value of Boogaard’s angle in males and females are 120°and 121°, respectively. The mean value of clival angle in males and females are 157°and 155°, respectively. There was no statistically significant difference (p > 0.05) between males and females in all three angles. Conclusion Knowledge about the normal angles will be an important tool in understanding the normal and abnormal skull base. Since the type of skull varies in accordance with race, the normal craniometric angle also varies in accordance with race. The present study tried to standardize the parameters of normal skull base angles for appropriate correction of the anomalies and uniform usage of terminology.
