Efficient operating room management is essential and requires precise surgery scheduling. We hypothesized that an estimation formula for the preparation time for anesthesia induction and surgery could be developed by incorporating anesthesia and surgical factors, as well as the 'clinical department,' into the formula. This retrospective observational study analyzed 12,528 scheduled surgical cases.

This study aimed to examine the effects of preventative measures against such injuries, proposing a potential standard for postural fixation in these surgeries. Methods Conducted at a medical center, from January 2017 to March 2023, this prospective cohort study involved participants aged 20 and above who underwent neurosurgical procedures in the park bench position under general anesthesia.

This study aimed to clarify the relationship between PI and central temperature during anesthesia induction, and the potential of PI in individualized and effective control of redistribution hypothermia. This prospective observational single center study analyzed 100 gastrointestinal surgeries performed under general anesthesia from August 2021 to February 2022.

In addition, the population of Lactobacillus in the vagina declines, increasing the risk of atrophic vaginitis, bacterial vaginosis, and genitourinary symptoms in the postmenopausal women. In this study, we evaluated the effects of Lactobacillus-containing feminine hygiene products on vaginal microbiome and genitourinary symptoms in pre- and postmenopausal women.

Age-related decline in estrogen affects population, leading to dominance of nonoptimal species and increased diversity in vaginal microbiota. In this study, we compared the differences between the vaginal microbiota of pre- and postmenopausal women.

This prospective observational study examined 64 patients scheduled to undergo general anesthesia in the lithotomy position from March 2021 to May 2022. The primary endpoint was the perfusion index (PI) of the lower limb before and after operating table rotation.

Perfusion index (PI) obtained with a pulse oximeter helps to assess peripheral perfusion dynamics by detecting the change in peripheral vascular tone. This study aimed to examine whether preoperative toe PI could predict the decrease in core temperature induced by spinal anesthesia during cesarean delivery.

Women with singleton pregnancies who underwent caesarean sections under spinal anaesthesia were included. Oxytocin was administered by an iv bolus injection (5 U) followed by an intravenous infusion (10 U of oxytocin in 500 mL normal saline); this was switched to just an intravenous infusion.

This is attributed in part to the echogenicity of the CGA becoming equal to that of the cervical stroma. The present study aimed to assess the usefulness of echogenicity in the CGA at term for predicting the time of spontaneous onset of labor.

The initial P. mirabilis isolate came from a midstream urine specimen containing large numbers of Gram-negative, rod-shaped organisms that failed to grow on both Drigalski agar and sheep blood agar incubated in ambient air.

In this study, we reevaluated the interaction of tacrolimus with P-gp in the rat small intestine, by evaluating its absorption from the rat small intestine and its modulating effect on the absorption of known P-gp substrates (digoxin, methylprednisolone, and vinblastine). Intestinal absorption of tacrolimus itself was as extensive as other P-gp modulators such as cyclosporine and verapamil.

The aim of this study was to determine the loperamide-induced sedative effect quantitatively and to investigate possible alterations in the pharmacokinetics of digoxin, a substrate for P-gp, in Japanese subjects.
Methods: Loperamide hydrochloride (2 mg) was administered orally to 26 subjects and the critical flicker-fusion frequency threshold (CFF) values were measured every 30 min separately by portable instrument.
Peripheral nerve injury often leads to neuropathic pain, which might involve sympathetic postganglionic nerve fiber sprouting in the dorsal root ganglion. Recent studies suggest the effectiveness of ropivacaine in blocking neuropathic pain. To determine if ropivacaine affects sympathetic sprouting, we used pheochromocytoma (PC-12) cells, which differentiate into neurons on exposure to nerve growth factor (NGF).

Previous reports suggested a correlation between accumulation of AGEs and production of vascular endothelial growth factor (VEGF) in human diabetic retina. However, the mechanisms involved were not revealed.
