#1
Juris Vanags, Renārs Erts, Guna Laganovska
BACKGROUND AND OBJECTIVE: This study sought to evaluate anterior capsulorhexis opening (ACO) reductions after surgery for a subluxated lens. Significant reduction of an ACO supports direct zonular involvement (capsular factors excluded by use of capsular tension rings [CTRs] and modern intraocular lens [IOLs]), and these findings question the long-term efficacy of subluxated lens surgery by means of cataract surgery. A small ACO due to lens mobility, non-enlargement of the ACO, and no lens epithelial cell washing due to an additional risk of further zonular damage were left as additional features to evaluate the possible outcomes of this simplified but still complicated surgery...

Giovanni Piumatti
BACKGROUND AND OBJECTIVE: The relationship between income and health in late life is well established, but the link between subjective financial wellbeing (SFW) and self-rated health (SRH) has been relatively ignored, especially among elderly in Europe. Adopting a longitudinal person-oriented analytical approach this study investigates the relationship between SFW and SRH in late life in Italy. MATERIALS AND METHODS: Analysis of the European Statistics on Income and Living Conditions survey (EU-SILC) for the period 2010-2013 in Italy examined these relationships at ages 65-78 (N=1268)...

BACKGROUND AND OBJECTIVE: Health care workers (HCWs) have a great background to promote their health - not only their professional knowledge on health but often also special equipment in their work environment. However, it is unclear if HCWs can use such infrastructure to promote their own health as well as what is their motivation to change their own lifestyles. Thus, the aim of the article was to describe workplace health promotion (WHP) situation in health care settings in Finland, Latvia, and Lithuania...

Sonja Smiljic
Endocardial endothelium (EE) is essential in the embryonic development of the heart, the optimal contractility and rhythm as well as the remodeling of the heart. Endocardial endothelium affect the contractility of cardiomyocytes through paracrine signaling substances such as nitric oxide (NO), endothelin (ET-1), prostaglandins (PGI2, PGF2, PGE2) and angiotensin II (ANG II). Typical lesions of endocardial endothelium have been described in atrial fibrillation, ischemia/reperfusion injury, cardiac hypertrophy, heart failure, sepsis, myocardial infarction, inflammation and thrombosis...

Glycemic homeostasis refers to glucose balance or control within circulation in living organisms. It is normally and largely compromised in diabetes. The compromise when exacerbated, leads to several complications including retinopathy, nephropathy and neuropathy which are collectively known as diabetic complications and are the principal actors in co-morbidity and eventual mortality often associated with diabetes. The ability of therapeutic compounds including medicinal plants to restore glycemic balance or homeostasis in hyperglycemic condition is an index of their antidiabetic function and relevance...

BACKGROUND AND OBJECTIVE: The subjective visual vertical (SVV) is a measure of a subject's perceived verticality, and a sensitive test of vestibular dysfunction. Despite this, and consequent upon technical and logistical limitations, SVV has not entered mainstream clinical practice. The aim of the study was to develop a mobile virtual reality based system for SVV test, evaluate the suitability of different controllers and assess the system's usability in practical settings. MATERIALS AND METHODS: In this study, we describe a novel virtual reality based system that has been developed to test SVV using integrated software and hardware, and report normative values across healthy population...

Ultrasound imaging in obstetrics and gynecology dates back to 1958 when The Lancet published the first article about the use of ultrasonography for fetal and gynecological assessments. It is now almost inconceivable, 60 years later, to think of effective performance in obstetrics and gynecology without the variety of ultrasound, for example, real time imaging, power and color Doppler, 3D/4D ultrasonography, etc. Such examinations facilitate the assessment of intrauterine fetal growth and development during pregnancy, provide alerts about the risk of pre-eclampsia and preterm birth, help identify anatomic reasons for infertility, diagnose ectopic pregnancies, uterine, ovary and tubal pathology...

Susac syndrome is characterized by a clinical triad of encephalopathy, branch retinal artery occlusion, and hearing loss. Due to the absence of the whole complex of the triad in the majority of cases at disease presentation, the syndrome often remains underdiagnosed and untreated. Headache is estimated to affect up to 80% of Susac syndrome patients, but the relevance of headache characteristics and profile is not yet clear. The proposed diagnostic criteria of the European Susac Consortium acknowledge headache as a possible brain manifestation if it is new, described as migrainous or oppressive, and precedes the other symptoms by not more than 6 months...

An anthropogenic human mummy curated in the Museum of the History of Medicine, Vilnius University, was recently examined by means of computed tomography. Although the mummy lacked data regarding its specific context and historical information on its identity and chronology, the investigation focused on the embalming method adopted to preserve it. Some pathological alterations were also recorded. This research appears to suggest that this body was prepared for educational and/or scientific purposes rather than funerary purposes...

BACKGROUND AND OBJECTIVE: The MTHFR gene encodes the methylenetetrahydrofolate reductase known to be involved in the homocysteine-methionine pathway. It has been reported that the deficiency of MTHFR activity may cause hyperhomocysteinemia which results in adverse pregnancy outcomes. Previous studies reported a correlation between the MTHFR gene polymorphisms (677 T/C and 1298 A/C) and lower MTHFR activity and its association with preterm birth in various populations. Since these results were conflicting, we analyzed the genetic association of MTHFR gene 677 T/C and 1298 A/C polymorphisms with preterm birth in Korean women...
