To assess the short-term and long-term effects of a delay in care on visual acuity (VA) in patients requiring intravitreal injections. This retrospective cohort study comprised patients with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), or retinal vein occlusion (RVO) receiving intravitreal injections. The visual and anatomic outcomes at the next completed visit and at the 1-year follow-up were studied. Of 1172 patients, 38% had a delay in care (mean 5.7 weeks). Compared with baseline, these patients lost VA (Early Treatment Diabetic Retinopathy Study letters) (mean -2.13 ± 0.49 SE) in the short-term ( = .0003) and had a thicker central subfield. Patients with no delay in care had a net VA gain (0.97 ± 0.39) ( = .0067). There was no difference in VA between 1 year and the baseline in either group. Long term, patients with nAMD in both groups had VA loss (no delay in care: -1.76 ± 0.60; delayed care: -2.44 ± 0.78) ( = .0005 and  = .0114, respectively). Patients with DME and no delay in care maintained gains in vision (4.68 ± 1.86) but those with delayed care did not (1.72 ± 2.24) ( = .0202 and  = .3756, respectively). In both groups, patients with RVO had no significant difference in vision from baseline. In patients requiring intravitreal injections, a delay in care of 5.7 weeks affected vision outcomes in the short term but not the long term.

Background: Alzheimer's Disease and Related dementias (ADRD) are disproportionately underdiagnosed, misdiagnosed, and undertreated in Latino/a/e/x populations living in the U.S. Latino/a/e/x families also experience low access to ADRD caregiver support services and high levels of depression.

Background Atherosclerotic cardiovascular diseases (ASCDs) are a significant health concern globally and in Sub-Saharan Africa (SSA), particularly for people living with HIV (PLWH). Hypertension, diabetes mellitus (DM), and dyslipidaemia significantly increase the risk of ASCDs, and integrating screening for these conditions in public health facilities remains challenging in Malawi. This study aimed to explore the barriers and facilitators to integrating screening for hypertension, DM and dyslipidaemia among adult PLWH at district hospital ART clinics in Southern Malawi.

Introduction: Early-onset Alzheimer's disease (EOAD) and late-onset Alzheimer's disease (LOAD) share similar amyloid etiology, but evidence from smaller-scale studies suggests that they manifest differently clinically. Current analyses sought to contrast the cognitive profiles of EOAD and LOAD.

Methods: Z-score cognitive-domain composites for 311 amyloid-positive sporadic EOAD and 314 amyloid-positive LOAD participants were calculated from baseline data from age-appropriate control cohorts.

To analyze the effects of exposure to life events and social support levels during different stages of pregnancy on low birth weight in offspring. From 2021 to 2023, pregnant women in early pregnancy who were registered with health cards in Linping District, Hangzhou City, were recruited and followed up. The Life Events Scale for Pregnant Women (LESPW) and Social Support Rating Scale (SSRS) were used to evaluate the exposure to life events and social support levels of pregnant women in early, middle and late pregnancy, respectively.

Exposure to organophosphorus nerve agents irreversibly inhibits acetylcholinesterase and may lead to cholinergic crisis and seizures. Although benzodiazepines are the standard of care after nerve agent-induced status epilepticus, when treatment is delayed for up to 30 min or more, refractory status epilepticus can develop. Adult male rodents are often utilized for evaluation of therapeutic efficacy against nerve agent exposure.
