Background: The influence of recombinant human prolactin (rh-PRL) added to Biolasol solution (concentration 1 μg/L) on selected markers (pH, osmolarity, Na(I) and K(I) concentration) and enzymatic activity (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and lactate dehydrogenase [LDH]) in perfundates was investigated during flushing and preservation of the isolated porcine kidneys.
Methods: The pH, osmolarity, concentration of K(I) and Na(I), and enzymatic activity were determined in perfundates collected after the 5th and 30th minutes of perfusion, after 24 hours of organ preservation, and in the 5th and 30th minutes of reperfusion. Kidneys had been flushed and stored in Biolasol (control group) and in Biolasol with rh-PRL (experimental group). Obtained results were compared with Biolasol solution.
Results: In the experimental group, the decrease in pH value in the 5th minute of reperfusion was noted. There was an increase in K(I) concentration, and Na(I) concentration decreased in the 5th and 30th minutes of reperfusion. ALT activity during perfusion and preservation increased, whereas at the 5th and 30th minutes of reperfusion it decreased. AST activity increased during perfusion and preservation and decreased in the 5th and 30th minutes of reperfusion. LDH activity was increased but decreased in the 5th minute of reperfusion.
Conclusions: Addition of 1 μg/L rh-PRL to Biolasol solution decreases pH and osmolarity values; influences Na(I) and K(I) concentration; increases ALT, AST activity during perfusion and preservation of organs; and decreases ALT, AST activity during reperfusion.

Additional Cladribine tablets treatment courses in multiple sclerosis patients. A retrospective observational study in Latin American countries.

The use of additional cladribine tablets treatment courses is becoming an option in patients with multiple sclerosis (MS) showing disease activity after treatment initiation. Despite the availability over the past year of several expert opinion guidance on the subject, there is a need for real-world assessment of the efficacy and safety of cladribine tablets in these patients. Thus, the aim of the present retrospective observational study is to describe the characteristics of patients that received additional treatment courses within the cohort of cladribine tablets-treated MS patients enrolled in the patient support program (PSP) Adveva® in Latin America countries.

Muscle mass has been traditionally assessed by measuring paraspinal muscle areas at the level of the third lumbar vertebra on computed tomography (CT). Neurological or neurosurgical patients seldom undergo CT scans of the lumbar region. Instead, temporal muscle thickness (TMT), cross-sectional area (TMA) and radiodensity measured from head CT scans are readily available measures of muscle mass and quality in these patient cohorts.

Background: Cannabinoid hyperemesis syndrome (CHS) is a syndrome of cyclic nausea and vomiting in the setting of chronic cannabis use. To date, only 11 cases of CHS in pregnancy have been reported.
Case Presentation: We describe two cases of uncontrolled vomiting in pregnancy due to CHS.
Ultrasound-guided Femoral - Sciatic Nerve Block for Lower Limb Long Bone Fractures.

Department of Anesthesia and Critical Care, Hanoi Medical University, Hanoi, Vietnam.
Background: Fractures of the long bones in the lower limbs are injuries that cause severe to extremely severe pain, posing risks to the patient's circulation, respiration, and even life. Pain management for patients with lower limb long bone fractures in the emergency department is critically important.
Objective: This study aimed to evaluate the feasibility of ultrasound-guided femoral and sciatic nerve blocks in patients with lower limb long bone fractures in the emergency department (ED).

Article Synopsis
- The study aimed to determine if pulse wave velocity (PWV) measured before surgery could predict hypotension during spinal anaesthesia in patients over 30 years old.
- Conducted at a Turkish university hospital, it compared patients with hypertension (HT group) to those with normal preoperative blood pressure (control group) during lower extremity surgeries.
- Results indicated that higher PWV was associated with increased rates of hypotension during spinal anaesthesia, suggesting PWV could serve as a reliable biomarker for predicting hypotensive episodes in hypertensive patients.
