Article Abstract
Objective: To determine the effect of the enteral nutrition algorithm on nutritional support in critically ill medical patients.
Methods: The quasi-experimental study was conducted at a medical Intensive Care Unit of a university hospital in central Anatolia region in Turkey from June to December 2008. The patients were divided into two equal groups: the historical group was fed in routine clinical applications, while the study group was fed according to the enteral nutritional algorithm. Prior to collecting data, nurses were trained interactively about enteral nutrition and the nutritional support algorithm. The nutrition of the study group was directed by the nurses. Data were recorded during 3 days of care. SPSS 22 was used for statistical analysis.
Results: The 40 patients in the study were divided into two equal groups of 20(50%) each. The energy intake of study group was 62% of the prescribed energy requirement on the 1st, 68.5% on the 2nd and 63% on the 3rd day, whereas in the historical group 38%, 56.5% and 60% of the prescribed energy requirement were met. The consumed energy of the historical group on the 1st 2nd and 3rd day was significantly different (p=0.020). In the study group, serum total protein and albumin levels decreased significantly (p<0.05), but pre-albumin and fasting blood glucose levels were not changed on the 1st and 4th day. In the historical group, any of the serum parameters did not change. Enteral nutrition-induced complications, duration of stay in intensive care unit were not significantly different between the groups (p>0.05).
Conclusions: The use of standard algorithms for enteral nutrition may be an effective way to meet the nutritional requirements of patients.

Safety and efficacy of personalised versus standard dosing of linezolid in patients with sepsis (SePkLin): a pragmatic, multicentre, randomised, controlled and superiority clinical trial protocol.

Introduction: Linezolid is a broadly used antibiotic to treat complicated infections caused by gram-positive bacteria. Therapeutic drug monitoring of linezolid concentrations is recommended to maximise its efficacy and safety, mainly haematological toxicity. Different pharmacokinetic/pharmacodynamic targets have been proposed to improve linezolid exposure: the ratio of the area under the concentration-time curve during a 24-hour period to minimum inhibitory concentration (MIC) between 80 and 120; percentage of time that the drug concentration remains above the MIC during a dosing interval greater than 85% and the trough concentration between 2 and 7 mg/L.

Diaphragm samples of the right side from 42 COVID-19 critically ill patients were analyzed and correlated with the type and length of mechanical ventilation (MV), ventilatory parameters, prone positioning, and use of sedative drugs. The mean number of fibers was 550±626.

Association between pupillary examinations and prognosis in patients with out-of-hospital cardiac arrest who underwent extracorporeal cardiopulmonary resuscitation: a retrospective multicentre cohort study.

Background: In some cases of patients with out-of-hospital cardiac arrest (OHCA) who underwent extracorporeal cardiopulmonary resuscitation (ECPR), negative pupillary light reflex (PLR) and mydriasis upon hospital arrival serve as common early indicator of poor prognosis. However, in certain patients with poor prognoses inferred by pupil findings upon hospital arrival, pupillary findings improve before and after the establishment of ECPR. The association between these changes in pupillary findings and prognosis remains unclear.

Introduction: There is conflicting evidence whether lower extremity arterial calcification coincides with coronary arterial calcification (CAC). The aims of this study were to investigate the associations between (1) femoral and crural calcification with CAC, and (2) femoral and crural calcification pattern with CAC.
Research Design And Methods: This cross-sectional study included 405 individuals (74% men, 62.
