Objectives: The first 3 rounds of the National Social Life, Health, and Aging Project (NSHAP) were in-person. Preparing for Round Four (R4), NSHAP began developing ways to collect complex questionnaire and biomeasure data remotely. R4 was scheduled to begin in 2020, but due to the coronavirus pandemic, NSHAP delayed R4 data collection and instead conducted a study on respondents' experiences during the pandemic, as well as pretests to strengthen NSHAP's remote data collection capability.

The pattern dystrophies (PDs) are a group of primarily autosomal dominant inherited macular diseases that cause the deposition of lipofuscin in retinal pigment epithelium (RPE) and may lead to significant vision loss in later life. Patients can develop choroidal neovascularization (CNV) and/ or geographic atrophy (GA) and for this reason they are often misdiagnosed as age-related macular degeneration (AMD). We presented a case of a 66-year-old patient complaining of vision loss in the right eye (RE) for 8 months.

A 60-year-old white woman presented to the emergency department with painless decrease of visual acuity in the left eye (LE). The diagnosis of a non-arteritic anterior ischemic optic neuropathy in the LE was established based on the clinical picture and the results of static perimetry, fluorescein angiography, visual evoked potential, and magnetic resonance imaging (MRI) of the brain and orbit. Six months later, the patient reported visual impairment in the right eye (RE).

We report a case of a 25-year-old woman with sudden and painless diminution in vision and central scotoma in her left eye (LE). She was a smoker and had been taking combined oral contraceptive (COC) pills for 1 year. On admission, the best-corrected visual acuity (BCVA) was 1,5/50 in the LE.

Choroidal neovascularization (CNV) is a very rare but sight-threatening complication of ocular syphilis. We reported the case of a 51-year-old woman who presented with a 2-week history of visual loss in the right eye (RE). Fundus examination demonstrated vitritis and the optic disc margin blurring.

Objectives: The third round (R3) of the National Social Life, Health, and Aging Project, a nationally representative, longitudinal survey of community-residing older adults, consisted of 4,777 in-person interviews and 6,100 completed visits to households to identify newly eligible respondents. It revisited respondents from the first rounds (Cohort 1), born in the years 1920 through 1947, and added new respondents (Cohort 2) born in the years 1948 through 1965. Coresidential romantic partners of both cohorts were also eligible.

Article Synopsis
  • Long-term use of topical carbonic anhydrase inhibitors (CAIs), especially those preserved with benzalkonium chloride (BAC), can negatively affect the eye's surface due to increased oxidative stress.
  • The study involved four groups of patients categorized by their use of antiglaucoma medications, with oxidative stress biomarkers in tear films measured after 6-12 months of treatment.
  • Results showed that patients using BAC-preserved CAIs had higher levels of oxidative stress markers and lower total sulfhydryl groups compared to those not using these preservatives, indicating a significant increase in oxidative stress in the tear film.

Article Synopsis
  • - The study aimed to assess how different types of glaucoma medications, specifically those with preservatives, impact various oxidative stress markers and protein levels in patients' tear film.
  • - Patients were categorized into four groups based on their use of either preservative-free or BAC-preserved timolol and brimonidine, with a control group included for comparison.
  • - Results showed that patients using BAC-preserved medications had higher oxidative stress indicators and protein modifications, suggesting a potential link to increased risk of dry eye disease over time.

Introduction: One of the major causes of cataract in diabetes is oxidative stress induced by reactive oxygen species (ROS). Nowadays, new substances with antioxidative properties that may prevent cataract development are needed. One such substance is caffeine - an alkaloid with well-documented antioxidative activity.

: Topically administered antiglaucoma medications, especially those containing benzalkonium chloride (BAC), may cause local adverse effects and compromise ocular surface. The aim of the study was to assess the effect of topical prostaglandin F2α analogs (PGAs): preservative-free latanoprost, BAC-preserved latanoprost, preservative-free tafluprost, and BAC-preserved bimatoprost, on selected oxidative stress parameters in the tear film. : The patients were divided into five groups: group C ( = 25) control group-subjects who did not use topical antiglaucoma medications, group L ( = 22)-patients using topical preservative-free latanoprost, group L+BAC ( = 25)-patients using topical BAC-preserved latanoprost, group T ( = 19)-patients using topical preservative-free tafluprost, and group B+BAC ( = 17)-patients using topical BAC-preserved bimatoprost.

Resveratrol is found in grapes, apples, blueberries, mulberries, peanuts, pistachios, plums and red wine. Resveratrol has been shown to possess antioxidative activity and a variety of preventive effects in models of many diseases. The aim of the study was to investigate if this substance may counteract the oxidative stress and polyol pathway in the lens of diabetic rats.

Objectives: We evaluated the safety and outcome of allo-HSCTs in myelofibrosis (MF).

Methods: A total of 27 patients with primary (n = 20) or secondary (n = 7) MF, aged 51 (21-63) yr, transplanted from HLA-matched related (59%) or unrelated (41%) donors were analyzed. Conditioning was reduced in 26 and myeloablative in one patient; and ATG was used in 25.

Introduction: Imatinib mesylate (IM) remains the treatment of choice for chronic myeloid leukemia (CML) showing a remarkable efficacy and offers a perspective for long disease-free survival. Due to prolonged administration of IM, the questions about the possible impact on the development of secondary malignancies (SM) are raised.

Objective: To investigate the incidence and clinical outcome of secondary malignancies during IM therapy for CML.

Thalidomide has indications for the treatment of several immune-related, neoplastic, and inflammatory diseases, in both adults and children. Despite numerous therapeutic indications for the application of thalidomide, the influence of that drug upon skeletal system has not been recognized. The aim of the present study was to investigate the effects of thalidomide on the osseous tissue in young rats.

Background: The methods used in treatment of osteoporosis induced by glucocorticosteroids are not effective enough. There is a need for new drugs which could be useful in counteracting the influence of glucocorticosteroids on osseous tissue. The aim of the present study was to investigate the effects of thalidomide on the development of osteoporosis induced by glucocorticoid (prednisolone) in rats.

Objectives: The aim of this report is to assess the safety of endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI). Although balloon angioplasty and stenting seem to be safe procedures, there are currently no data on the treatment of a large group of patients with this vascular pathology.

Methods: A total of 564 endovascular procedures (balloon angioplasty or, if this procedure failed, stenting) were performed during 344 interventions in 331 CCSVI patients with associated multiple sclerosis.

The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.

It has been established that sows up- or down-regulate their milk production as the frequency of nursings is changed. The amount of udder massage by piglets might also influence milk production. To investigate whether these effects are associated with changes in prolactin or insulin levels, we enforced five sows each to nurse either every 35 min (MIN35) or every 70 min (MIN70) over a 26- to 28-hr period.
