Strategies for the use of Ginkgo biloba extract,EGb 761®, in the treatment and management of mild cognitive impairment in Asia: Expert consensus

BackgroundMild cognitive impairment (MCI) is a neurocognitive state between normal cognitive aging and dementia, with evidence of neuropsychological changes but insufficient functional decline to warrant a diagnosis of dementia. Individuals with MCI are at increased risk for progression to dementia; and an appreciable proportion display neuropsychiatric symptoms (NPS), also a known risk factor for dementia. Cerebrovascular disease (CVD) is thought to be an underdiagnosed contributor to MCI/dementia. The Ginkgo biloba extract, EGb 761^®, is increasingly being used for the symptomatic treatment of cognitive disorders with/without CVD, due to its known neuroprotective effects and cerebrovascular benefits.AimsTo present consensus opinion from the ASian Clinical Expert group on Neurocognitive Disorders (ASCEND) regarding the role of EGb 761^® in MCI.Materials & MethodsThe ASCEND Group reconvened in September 2019 to present and critically assess the current evidence on the general management of MCI, including the efficacy and safety of EGb 761^® as a treatment option.ResultsEGb 761^® has demonstrated symptomatic improvement in at least four randomized trials, in terms of cognitive performance, memory, recall and recognition, attention and concentration, anxiety, and NPS. There is also evidence that EGb 761^® may help delay progression from MCI to dementia in some individuals.DiscussionEGb 761^® is currently recommended in multiple guidelines for the symptomatic treatment of MCI. Due to its beneficial effects on cerebrovascular blood flow, it is reasonable to expect that EGb 761^® may benefit MCI patients with underlying CVD.ConclusionAs an expert group, we suggest it is clinically appropriate to incorporate EGb 761^® as part of the multidomain intervention for MCI.     

Ocular surface effects of repeated application of povidone iodine in patients receiving frequent intravitreal injections

Background: The aim of this study was to investigate the patient reported symptoms and objective signs of tear film and ocular surface abnormalities experienced by patients undergoing repeated exposure to povidone iodine as a consequence of requiring frequent intravitreal injections for wet macular degeneration.

Methods: This was a prospective study of consecutive patients who had received recent povidone 5% solution for sterile preparation of intravitreal injection less than 3?months prior to inclusion with a total of at least 3 intravitreal injections for macular degeneration. Each patient had one study eye which was undergoing regular intravitreal injection and a fellow eye which was not undergoing any injections. Each patient underwent evaluations of various tear film parameters on a single occasion for both eyes. The primary outcome was severity of dry eye symptoms as measured by the Schein dry eye questionnaire. The secondary outcomes were tear film osmolarity and corneal punctate staining using the Oxford Grading Scale.

Results: A total of 90 patients were included in the study. 43.3% n?=?39, were using ocular lubricating medication on a regular basis. A significantly greater proportion of study eyes had a Schein dry eye questionnaire score of 7 or higher; 12.2%, n?=?11 amongst study eyes vs 4.4%, n?=?4 amongst control, fellow eyes (p?p?=?0.087). The study eyes had statistically significantly worse corneal staining as determined by the Oxford grading scale; 0.69 in study eyes vs 0.58 in control, fellow eyes (p?=?0.02).

Conclusion: Our results confirm the detrimental impact of repeated application of povidone iodine for intravitreal injection procedures on symptoms of dry eyes as experienced and reported by patients.     

Gallstone ileus one quarter of a century post cholecystectomy

Gallstone ileus is a rare but potentially serious complication of cholelithiasis. It is usually preceded by history of biliary symptoms. It usually occurs as a result of a large gallstone creating and passing through a cholecysto-enteric fistula. Most of the time, the stone will pass the GI tract without any problems, but large enough stones can cause obstruction. The two most common locations of impaction are the terminal ileum and the ileocaecal valve because of the anatomical small diameter and less active peristalsis. We present an unusual case of small bowel obstruction secondary to gallstone ileus 24 years after an open cholecystectomy.     

Postural blood pressure electrocardiographic changes are associated with falls in older people

Objectives

To determine the magnitude of postural blood pressure change, differences in ECG between fallers and non-fallers were measured. Postural blood pressure change is associated with symptoms of dizziness, presyncope, and syncope.

Methods

In this cross-sectional study were included participants from The Malaysian Falls Assessment and Intervention Trial: fallers, aged 65 years or older with two or more falls or one injurious fall in 12 months, from a teaching hospital; and non-fallers, aged 65 years and older found through word-of-mouth and advertising. Noninvasive beat-to-beat blood pressure was measured at 10 min supine rest and 3 min standing. The maximal drop in systolic and diastolic pressure was calculated from a 12-lead ECG interpreted by a cardiologist. Basic demographics, medical history, and symptoms of dizziness, presyncope, and syncope were recorded for all patients.

Results

We recruited 155 fallers and 112 non-fallers. Fallers had a significantly longer PR interval (179 ± 32 vs. 168 ± 27 ms, p = 0.013) and a longer corrected QT interval (449 ± 41 vs. 443 ± 39 msec, p = 0.008), and larger change in SBP (28 ± 14 vs. 19 ± 9 mmHg, p < 0.001) with posture change. SBP drop of ≥30mmHg associated with recurrent and injurious falls [odds ratio [95 % confidence interval] = 7.61 (3.18–18.21)]. The changes remained significant after adjustment for symptoms of dizziness, presyncope and syncope.

Interpretation

Older individuals with recurrent and injurious falls have significantly longer PR and QT intervals and larger SBP reduction with posture change as compared to non-fallers, and these are not explained by the presence of dizziness, presyncope, or syncope. SBP cut-off of ≥30mmHg considered for postural measurements using continuous BP monitors, the significance of this value needs to be evaluated.

     

Is there a changing trend in surgical management of gastroesophageal reflux disease in children？

Gastroesophageal reflux disease (GORD) is a pathological process in infants manifesting as poor weight gain, signs of esophagitis, persistent respiratory symptoms and changes in neurobehaviour. It is currently estimated that approximately one in every 350 children will experience severe symptomatic gastroesophageal reflux necessitating surgical treatment. Surgery for GORD is currently one of the common major operations performed in infants and children. Most of the studies found favour laparoscopic approach which has surpassed open antireflux surgery as the gold standard of surgical management for GORD.However, it must be interpreted with caution due to the limitation of the studies, especially the small number of subject included in these studies. This review reports the changing trends in the surgical treatment of GORD inchildren.
