Can emergency physicians accurately distinguish retinal detachment from posterior vitreous detachment with point-of-care ocular ultrasound?
The objective of this study was to determine the ability of emergency physicians to differentiate RDs from PVDs using point-of-care (POC) ocular ultrasound.

Syphilis and vision loss: A role for point-of-care ultrasound
We present a case of a 33-year-old man with recently identified syphilis and HIV, who was diagnosed with bilateral retinal detachments (RDs) with the help of point-of-care ultrasound (POCUS) in the setting of panuveitis (preventing visualization with direct fundoscopy).

The epidemiology of diabetes in the Waikato region: an analysis of primary care data
DISCUSSION We found that management of T2DM was suboptimal, with measures for many patients not meeting clinical targets. Support should be provided to improve weight and glycaemic management, particularly for Māori, females and younger patients.PMID:33785110 | DOI:10.1071/HC20067

Why I Seldom Recommend Vitamins or Supplements
By HANS DUVEFELT People here in northern Maine, as in my native Sweden, don’t get a whole lot of natural sunlight a good part of the year. As a kid, I had to swallow a daily spoonful of cod liver oil to get the extra vitamin D my mother and many others believed we all needed. Some years later, that fell out of fashion as it turned out that too much vitamin A, also found in that particular dubious marine delicacy, could be harmful. This is how it goes in medicine: Things that sound like a good idea often turn out to be not so good, or even downright bad for you. Other vitamins, like B12, can also cause harm: Exce...

Predictors of attendance at diabetic retinopathy screening among people with type 2 diabetes: Secondary analysis of data from primary care
CONCLUSIONS: Most patients managed in a structured diabetes care programme in primary care attended screening. Those with on target blood glucose control, those who were on oral or injectable medication or had been seen by a DNS were more likely to attend for annual screening. Of those who attended screening, almost one-third attended other screening services and so were not availing of the national programme, which is free, quality assured and has an integrated treatment arm.PMID:34518110 | DOI:10.1016/j.pcd.2021.08.004

Management of Eye Trauma for the Primary Care Physician
This article elucidates a methodological approach to eye trauma. The first step is to address any life-threatening conditions. Then a focused history and exam is discussed, starting externally. Then, key history, physical, pathophysiology, and basic management of common, serious eye injuries are discussed: chemical injury, orbital fractures, open globe, traumatic hyphema, retinal detachment, traumatic optic neuropathy, and eyelid laceration. Finally, we highlight the practicality of telemedicine for areas where ophthalmology coverage is lacking.

Vitamin A Kinetics in Neonatal Rats vs. Adult Rats: Comparisons from Model-Based Compartmental Analysis Critical Review
A critical role for vitamin A (VA) in development is well established, but still relatively little is known about whole-body VA metabolism in early postnatal life. Recently, methods of mathematical modeling have begun to shed light on retinol kinetics in the postnatal growth period and on the effect of retinoid supplementation on retinol kinetics. Comparison of kinetic parameters from tracer studies in neonatal rats with those previously determined in models of VA metabolism in the adult suggests both similarities and differences in the relative transfer rates of plasma retinol to extrahepatic tissues, resulting in similar...

Vitamin “G”arden: a qualitative study exploring perception/s of horticultural therapy on a palliative care ward
ConclusionsOur study showed that the availability of HT was highly appreciated by the patients as well as by the palliative care team. Nevertheless, the dropout rate was high, and therefore, it might be more feasible to integrate green spaces into palliative care wards.
