Background: Maternity nurses are frontline health professionals in the COVID-19 pandemic who may confront life-altering challenges. Studies that evaluated the impact of COVID-19 on maternity nurses’ daily lifestyles are limited. Objective: The aim of this study was to examine the changes in health-enhancing behaviors, such as eating habits and lifestyle behaviors, during the COVID-19 pandemic among nurses working in a maternity hospital. Methods: This was a cross-sectional study that surveyed maternity nurses working in a major government maternity hospital in Kuwait. Data were collected between January and February 2021. Results: A total of 336 participants completed the questionnaire. Normal weight was perceived by 88 (26.2%) of the participants, while 56 (16.7%) had a Body Mass Index indicating obesity. Weight gain during the pandemic was reported by 128 (38.1%) participants and 91 (27.1%) of the sample gained one to three kilograms. The findings showed low adherence to the Mediterranean diet 5.3 ± 2.5 points. Sleep hours decreased significantly during the crisis, with 113 (33.6%) of participants sleeping 7 to 9 hours during the COVID-19 situation compared to 136 (40.5%) before the pandemic (p Conclusion: Maternity nurses revealed low adherence with the healthy diet, with almost a third of participants having self-reported weight gain. Further, the sleeping patterns and the practicing of physical activities were negatively affected by COVID-19 pandemic.

Several pupil filtering techniques have been developed in the last few years to obtain transverse superresolution （a narrower point spread function core）. Such a core decrease entails two relevant limitations： a decrease of the peak intensity and an increase of the sidelobe intensity. Here, we calculate the Strehl ratio as a function of the core size for the most used binary phase filters. Furthermore, we show that this relation approaches the fundamental limit of the attainable Strehl ratio at the focal plane for any filter. Finally, we show the calculation of the peak-to-sidelobe ratio in order to check the system viability in every application.

Dear Editor, The scarce number of secondary spermatocytes in human seminiferous tubules and the complexity of analyzing chromosomes at metaphase II are the main causes of the limited knowledge we have about chromosome characteristics at this stage. In this study, we have performed a comprehensive analysis of meiotic abnormalities in metaphase II spermatocytes combining Leishman＇s staining protocols and multiplex fluorescent in situ hybridization procedures. Results indicated that infertile individuals showed different susceptibilities to meiotic abnormalities in secondary spermatocytes without a preferentially effect on any particular chromosome.

Invasive rats ( spp.) are known to have pervasive impacts on island birds, particularly on their nesting success. To conserve or restore bird populations, numerous invasive rat control or eradication projects are undertaken on islands worldwide. However, such projects represent a huge investment and the decision-making process requires proper assessment of rat impacts. Here, we assessed the influence of two sympatric invasive rats ( and ) on native bird eggs in a New Caledonian rainforest, using artificial bird-nest monitoring. A total of 178 artificial nests containing two eggs of three different sizes were placed either on the ground or 1.5 m high and monitored at the start of the birds' breeding season. Overall, 12.4% of the nests were depredated during the first 7 days. At site 1, where nests were monitored during 16 days, 41.8% of the nests were depredated. The main predator was the native crow , responsible for 62.9% of the overall predation events. Rats were responsible for only 22.9% of the events, and ate only small and medium eggs at both heights. Our experiment suggests that in New Caledonia, predation pressure by rats strengthens overall bird-nest predation, adding to that by native predators. Experimental rat control operations may allow reduced predation pressure on nests as well as the recording of biodiversity responses after rat population reduction.
