Effects of Progesterone on Isoflurane Requirement for Balance Disturbance and Loss of Righting Reflex in Male Mice.

Introduction It has been known that progesterone has central effects, as measured by minimum alveolar concentration in various experimental settings. Previously, we showed that progesterone reduces the sevoflurane requirement for the loss of righting reflex (LORR) using male mice. However, the combination of progesterone and isoflurane has not been studied.

Relationship between oriT length and efficiency of RP4-mediated conjugation from Escherichia coli to Gram-positive bacteria.

In RP4 conjugation, approximately 350 bp of the origin of transfer (oriT) is required for transfer. Within this oriT, there are binding regions for the transfer-related proteins TraI, TraK, and TraJ. We investigated the influence of deleting each protein-binding region within oriT on transfer efficiency in Escherichia coli, Streptomyces lividans, and Bacillus subtilis.

Cardiac arrest after acute pulmonary edema in pregnancy is an uncommon event but one with a potentially disastrous outcome. We report the case of a pregnant woman with preeclampsia who presented with rapidly advancing pulmonary edema and subsequently went into cardiac arrest on arrival at the operating room. A perimortem cesarean section was performed in addition to cardiopulmonary resuscitation and anesthesia.

Novel Variant in the Neonate of a Mother with Gestational Diabetes Mellitus Showing Left Ventricular Hypertrophy and Noncompaction.

Background: Left ventricular hypertrophy (LVH) is a well-recognized cardiac dysfunction in infants of mothers with gestational diabetes mellitus (GDM). Left ventricular noncompaction (LVNC) is a cardiomyopathy that is morphologically characterized by numerous prominent trabeculations and deep intertrabecular recesses on cardiovascular imaging. However, there have been no case reports on neonates of mothers with GDM showing LVH and LVNC.

Management of Labor and Anesthesia in a Patient With a History of Spontaneous Intracranial Hypotension: A Case Report With Literature Review.

Spontaneous intracranial hypotension (SIH) is a rare disorder characterized by continuous or intermittent cerebrospinal fluid (CSF) leakage from the CSF cavity, which causes symptoms such as headache or neck pain upon standing. However, no well-established measures concerning the type of delivery and anesthesia for pregnant women with a history of SIH have been reported. A woman had developed SIH 9 years earlier from lifting luggage into an overhead bin with stretching movements, which required continuous saline epidural infusion for recovery.

Tetra-μ-selen-ido-1:2:3κ;1:2:4κ;1:3:4κ;2:3:4κ-tetrakis-[(η-methyl-cyclo-penta-dien-yl)molybdenum(III)](6 ).

The title cluster compound, [Mo(η-CHMe)(μ-Se)], was synthesized from the reaction of [Mo(η-CHMe)(CO)] with grey selenium in refluxing xylene solution under a nitro-gen atmosphere. The complete cluster is generated by a crystallographic twofold axis and contains an MoSe cubane-like core surrounded by four η-methylcyclo-pentadienyl ligands. In the core, the four molybdenum atoms are connected to each other to form a tetra-hedron, with a selenium atom capping each face.

Estimation of Left and Right Ventricular Ejection Fractions from cine-MRI Using 3D-CNN.

Cardiac function indices must be calculated using tracing from short-axis images in cine-MRI. A 3D-CNN (convolutional neural network) that adds time series information to images can estimate cardiac function indices without tracing using images with known values and cardiac cycles as the input. Since the short-axis image depicts the left and right ventricles, it is unclear which motion feature is captured.

The Ropivacaine Concentration Required for Ultrasound-Guided Rectus Sheath Block in Pediatric Patients Undergoing Single-Incision Laparoscopic Hernia Repair: A Sequential Allocation Dose-Finding Study.

Background: The local anesthetic concentration required for ultrasound-guided rectus sheath block (RSB) in children remains unknown. Knowledge of appropriate ropivacaine concentration can help clinicians reduce local anesthetic toxicity risk when performing ultrasound-guided RSB in children. This study aimed to determine the appropriate ropivacaine concentration for ultrasound-guided RSB in children undergoing laparoscopic inguinal hernia repair.

Salvage surgery for advanced non-small cell lung cancer following previous immunotherapy: a retrospective study.

Background: The development of systemic chemotherapy including immune checkpoint inhibitors (ICIs) has provided patients with unresectable advanced non-small cell lung cancer (NSCLC) an opportunity to undergo surgical intervention after initial treatment. However, no consensus regarding the indication for salvage surgery in these patients has been reached.

Methods: We conducted a retrospective study of patients who underwent salvage surgery for advanced NSCLC (cStage IIIA-IVB) after treatment with ICIs from January 2018 to December 2022 at Aizu Medical Center and Fukushima Medical University Hospital.

Psychological distress in later life and incident dementia: The Ohsaki Cohort 2006 Study.

Background: The role of reverse causation in the association between psychological distress and incident dementia remains unclear. We investigated whether psychological distress is a risk factor for, or prodromal symptom of, dementia.

Methods: A longitudinal analysis of psychological distress with incident dementia was conducted among 12,076 Japanese individuals (age ≥65 years) followed for 5.

Successful Nerve Block Therapy for Lateral Cutaneous Nerve Entrapment Syndrome (LACNES) Triggered by Exercise.

This report presents a case of a 59-year-old man who experienced pain in the left abdomen during abdominal exercises, which gradually improved. Pain recurred in the same area one year later and gradually worsened, rendering him unable to work. The strongest tender point, with a positive Carnett's sign, was noted on the flank.

Dynamics of Interaction among Professionals, Informal Supporters, and Family Caregivers of People with Dementia along the Dementia Care Pathway: A Nationwide Survey in Japan.

This study aims to clarify the dynamics of information provision and human interaction to satisfy the needs of family caregivers. A questionnaire survey consisting of items on information received at and after diagnosis, persons and resources consulted, needs, and caregiver-oriented outcomes was conducted. Among the respondents, 2295 individuals who were caring for people with dementia were divided into quartiles by the time after diagnosis, and differences were statistically analyzed.

Comparison of postoperative analgesic effects of thoracic epidural analgesia and rectus sheath block in laparoscopic abdominal surgery: A randomized controlled noninferiority trial.

Introduction: In the Enhanced Recovery After Surgery program, abdominal wall blocks are strongly recommended as postoperative multimodal analgesia for laparoscopic abdominal surgery. The purpose of this study was to compare the efficacy of single-shot rectus sheath block (RSB) with that of thoracic epidural analgesia (TEA) as a method of multimodal analgesia in patients receiving conventional laparoscopic abdominal surgery.

Methods: A noninferiority comparison was performed.

[Clinical Features of Endocrine Disorders with Immune Checkpoint Inhibitor in Patients with Non-Small Cell Lung Cancer].

Immune checkpoint inhibitors(ICIs)could cause immune-related adverse events(irAEs), of which endocrine disorders are relatively common. Symptoms include fatigue, anorexia, and shock, making diagnosis and treatment difficult. This study aimed to analyze the characteristics of patients with non-small cell lung cancer concomitant with endocrine disorders as irAEs.

Wnt/β-Catenin Signaling and Resistance to Immune Checkpoint Inhibitors: From Non-Small-Cell Lung Cancer to Other Cancers.

Lung cancer is the leading cause of cancer-related deaths worldwide. The standard of care for advanced non-small-cell lung cancer (NSCLC) without driver-gene mutations is a combination of an anti-PD-1/PD-L1 antibody and chemotherapy, or an anti-PD-1/PD-L1 antibody and an anti-CTLA-4 antibody with or without chemotherapy. Although there were fewer cases of disease progression in the early stages of combination treatment than with anti-PD-1/PD-L1 antibodies alone, only approximately half of the patients had a long-term response.

Traumatic Hemomediastinum and Hemothorax in a Patient With Totally Corrected Tetralogy of Fallot.

An 18-year-old Japanese youth was transferred to our emergency department because of a traffic accident. He had a past history of total correction for tetralogy of Fallot as an infant. Chest computed tomography revealed hemomediastinum and hemothorax.

Multipolar radiofrequency ablation via three bipolar electrodes with C-arm type X-ray fluoroscopy assistance for hepatocellular carcinoma: An observational study.

The present study aimed to investigate the therapeutic efficacy and safety of the insertion technique of 3 bipolar electrodes in patients with hepatocellular carcinoma (HCC), using C-arm type X-ray fluoroscopy-assisted ultrasonography (US) in guiding a multipolar radiofrequency ablation (RFA) system. Seventy-three patients with HCC treated with a multipolar RFA system (1 electrode, n = 2; 2 electrodes, n = 56; 3 electrodes, n = 17) were enrolled in this retrospective cohort study. To analyze their therapeutic outcome in this study, we divided among 17 patients using 3 electrodes into 2 subgroups: the C-arm type X-ray fluoroscopy-assisted (n = 7) and the US-guided alone groups (n = 10).

Ectopic adrenocorticotropic hormone-secreting carcinoid with solitary cryptococcosis in the lungs.

Background: Carcinoid tumors can on rare occasions ectopically produce adrenocorticotropic hormone (ACTH), causing Cushing's syndrome, and patients could become immunocompromised. Care must therefore be taken regarding infectious complications. In particular, ACTH-producing pulmonary carcinoid is not easy to diagnose by itself, and when combined with pulmonary nodules as infectious foci, each is very difficult to diagnose.
