Is adherence to the Mediterranean diet (MedDiet) associated with better IVF performance in women attempting fertility? Greater MedDiet, defined using validated score (MedDietScore), was a higher likelihood of achieving clinical pregnancy and live birth among non-obese <35 years age. Diet impacts fertility certain nutrients food groups appear have greater effect on reproductive health, but there are relatively few published data role dietary patterns, MedDiet particular, assisted performance....

Is adherence to the Mediterranean diet (MedDiet) associated with better semen quality in men of subfertile couples attempting fertility?Greater MedDiet, as assessed through validated score (MedDietScore), was significantly higher sperm concentration, total count and motility.A-posteriori dietary pattern approaches have revealed that patterns characterized by high intakes fruits, vegetables, whole grains, fish low intake meat are quality. Yet, whether MedDiet is profile remains largely...

The provision of effective emergency telemedicine and home monitoring solutions are the major fields interest discussed in this study. Ambulances, Rural Health Centers (RHC) or other remote health location such as Ships navigating wide seas common examples possible sites, while critical care telemetry follow-ups important issues telemonitoring. In order to support above different growing application we created a combined real-time store forward facility that consists base unit (mobile) unit....

Although several studies have reported an association between malnutrition and the risk of severe complications after abdominal surgery, there been no evaluating use Global Leadership Initiative on Malnutrition (GLIM) criteria for predicting postoperative pulmonary (PPCs) following major surgery in cancer patients. This study aimed to investigate among diagnosis by GLIM criteria, PPCs 90-day all-cause mortality rate We prospectively analyzed 218 patients (45% male, mean age 70.6 ± 11.2...

Abstract Background Before the pandemic of coronavirus disease (COVID-19), rapidly improving acute respiratory distress syndrome (ARDS), mostly defined by early extubation, had been recognized as an increasingly prevalent subphenotype (making up 15–24% all ARDS cases), associated with good prognosis (10% mortality in ARDSNet trials). We attempted to determine prevalence and persistent severe related COVID-19. Methods included consecutive patients COVID-19 receiving invasive mechanical...

Patients undergoing ileostomy surgery often experience electrolyte disturbances and dehydration, especially during the first post-operative period. Recently, research has also begun on how newly constructed affects patient's nutritional status.The aim of present pilot study was to assess status patients before after construction as well nutrition-related factors.This a study. The sample consisted 13 adult diagnosed with colorectal or colon cancer who underwent scheduled surgery. evaluation...

Nonenumerative path-delay fault coverage estimation for combinational circuits estimates the of a given test set without explicit enumeration all paths in circuit. In recent nonenumerative method, it was proposed that C lines be located circuit so forms cut and no belong to same path. Each line defines subcircuit consisting contain line. Fault may obtained by working on subcircuits double-counting faults. The main result this paper is polynomial time algorithm finding maximum cardinality C....

In clinical settings, standing height measurement is often difficult to perform due patients’ inability stand upright. Height prediction equations derived from measurements of the length other body segments have been published; however, they are not readily applicable all populations since ethnic differences affect relationship between and segment length. This cross-sectional study aimed examine accuracy using Malnutrition Universal Screening Tool (MUST) predictive among Greek patients...

In this paper we present an efficient test pattern generator for robust path delay faults, which call ATPD. Our CAD tool detects much faster more faults than any other existing nonenumerative approach. ATPD generates patterns a non necessarily polynomial number of faults. The nature the problem indicates that to be it must count nonenumeratively additional paths detected by each generated pair patterns. and determines covered in novel way combines these two phases effectively.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) ABCD classification tool has been used to assess the symptom burden and exacerbation risk of patients with chronic obstructive pulmonary disease (COPD). An area requiring further exploration is relationship between GOLD classification's basic components measurements acquired by Sit-to-Stand tests (STST). We aimed study STST component tool. This was conducted on a sample 42 COPD subjects patient history, assessment test (CAT)...

This paper presents a nonenumerative automatic test pattern generator for robustly testable path delay faults. In contrast to earlier work by I. Pomeranz, et al. (see IEEE Trans. Computer-Aided Design, vol. 14, p. 1505-15, Dec. 1995), the takes into consideration conditions robust propagation while sensitizing sets of paths. increases probability testing them with single test. Novel algorithms are described which identify that contain many such potentially compatible The number detected...
