OBJECTIVES To determine the efficacy of refractive correction alone and patching treatment with near activities on amblyopia associated with myopic anisometropia in children aged 4 to less than 14 years. The associations of visual acuity (VA) improvement with age,degree of anisometropia, patching compliance, presence of strabismus, and presence of eccentric fixation were also investigated. ME...

Vitamin A (VA) fortification of cooking oil is considered a cost-effective strategy for increasing VA status, but few large-scale programs have been evaluated. We conducted representative surveys in Yaoundé and Douala, Cameroon, 2 years before and 1 year after the introduction of a mandatory national program to fortify cooking oil with VA. In each survey, 10 different households were selected w...

BACKGROUND In healthy volunteers, the single-breath diffusing capacity of the lung for carbon monoxide (DLCO) decreases and DLCO normalized per liter alveolar volume (VA; DLCO/VA) increases if VA is decreased. We hypothesized that comparison of DLCO/VA with its predicted value at predicted total lung capacity (TLC) will result in an underestimation of the diffusion disorder in patients with a r...

Background: Vitamin A (VA; retinol) supplementation is widely used to reduce child mortality in low-income countries. However, existing research suggests that supplementation with VA alone may not be optimal for infants. Objective: We compared the effect of VA with VA combined with retinoic acid (VARA) on retinol uptake and turnover in organs of neonatal rats raised under VA-marginal conditions...

Hospitalization to initiate hemodialysis (HD) through temporary catheterization and subsequent creation of permanent vascular access (VA) is costly. Therefore, we studied the influence of the timing of VA creation on medical expenses, length of stay (LOS) and 1-year primary patency rate in incident HD patients. We analyzed the medical expenses associated with hospitalization and LOS at VA creat...

BACKGROUND More than half of veterans who use Veterans Health Administration (VA) care are also eligible for Medicare via disability or age, but no prior studies have examined variation in use of outpatient services by Medicare-eligible veterans across health system, type of care or time. OBJECTIVES To examine differences in use of VA and Medicare outpatient services by disability-eligible or...

Chaharmahal and Bakhtiari Province is one of the 31 provinces of Iran and located on the southwestern part of the country. Its capital is Shahrekord. It has an area of 16,332 square kilometers and a population of 857,910. To study of human development used the Surplus Biocappacity (SB) and Human Development Index (HDI). This research accrued in the shahr-e-kord, Boroojen, Farsan, Ardal, Lordega...
