Purpose: To evaluate the visual, refractive, contrast sensitivity, and aberrometric outcomes as well as the patient quality of life and photic phenomena disturbances after cataract surgery with implantation of a new trifocal toric intraocular lens (IOL).
Settings: Premium Clinic, Regional Hospital in Havlickuv Brod, Czech Republic, and Vissum and Universidad Miguel Hernández, Alicante, Spain.
Design: Prospective consecutive series of cases.
Methods: The study involved eyes with corneal astigmatism of 1.25 D or more that were having cataract surgery with implantation of the trifocal toric IOL AT Lisa tri toric 939MP (Carl Zeiss Meditec). Visual outcomes and astigmatic changes analyzed by Alpins vector analysis were evaluated at 3 months postoperatively. Contrast sensitivity, quality of life, and photic phenomena were also evaluated.
Results: The study involved a total of 30 eyes of 16 patients, age 37 to 64 years. A significant improvement with surgery was observed in uncorrected distance, intermediate, and near visual acuity (P ≤ .01). A significant decrease in the refractive cylinder was observed postoperatively (P < .01), with all eyes showing a postoperative astigmatism below 1.00 D. The difference between targeted and surgically induced astigmatism was small (0.06 ± 0.30 D) but statistically significant (P = .04). The mean magnitude of angle of error was 5.80 ± 8.47 degrees. The low levels of higher-order aberrations found postoperatively were consistent with the good levels of contrast sensitivity achieved. Regarding quality of life, low to moderate levels of difficulty in performing various types of vision-related tasks were found.
Conclusions: The trifocal toric IOL evaluated provides effective restoration of visual function after cataract surgery, with associated high levels of visual acuities and quality of life.

Hepatopulmonary syndrome (HPS) is a rare pulmonary vascular complication of chronic liver disease characterized by dilatation of pulmonary capillaries leading to vascular shunting and systemic hypoxemia. Diagnosis of HPS requires documentation of intrapulmonary vasodilation (IPVD), the two most common imaging studies performed for the detection of IPVD include transthoracic contrast echocardiography (TTCE) and 99m-Tc-macroaggregated albumin scintigraphy (99mTc-MAA scan). TTCE has high sensitivity and thus, is the preferred initial investigation, while 99mTc-MAA scan is highly specific and plays an adjuvant role in diagnosis.

However, increasing human land use represents a major threat to native AMF globally. Characterizing the loss of AMF diversity remains challenging because many taxa are undescribed, resulting in poor documentation of their biogeography and family-level disturbance sensitivity.

Background: About 30% of ischemic strokes do not have a clear cause, which is called cryptogenic stroke (CS). Increasing evidence suggests a potential link between CS and right-to-left shunt (RLS). RLS may lead to CS via paradoxical embolic mechanism.

A 2019 nationwide study in Japan revealed the predominant methicillin-resistant Staphylococcus aureus (MRSA) types in bloodstream infections (BSIs) to be sequence type (ST)8-carrying SCC type IV (ST8-MRSA-IV) and clonal complex 1-carrying SCC type IV (CC1-MRSA-IV). However, detailed patient characteristics and how these MRSA types evolve over time remain largely unknown. In this long-term single-center study, MRSA strains isolated from blood cultures at Nagasaki University Hospital from 2012 to 2019 were sequenced and analyzed.
