[Investigation the contents of employment consultation and support in a cancer center hospital].

OBJECTIVES: This study aimed to analyze and categorize the actual situation of employment consultation and support according to consultation times or employment status at the Consultation Support Center of the National Cancer Center Hospital of Japan. METHODS: We retrospectively analyzed the patient backgrounds, consultation contents, and the number of employment consultation cases conducted at the Consultation Support Center of the National Cancer Center Hospital during a 6-month period from May to December 2018. RESULTS: During the study period, 117 patients (male: female = 46:71) visited the Consultation Support Center. The median age of patients was 48 years old. The most common primary cancer site was the breast in 28 patients followed by the lung in 16 patients, and then gynecologic cancer in 10 patients. The most common cancer treatment was chemotherapy in 53 patients (45.3%), and 12 patients (10.2%) were recurrent patients. Fifty-two patients were in regular employment, 24 were unemployed, 17 were of unknown employment status, 16 were in non-regular employment, and 8 were classified/categorized as other. In terms of working status, 40 were on leave, 35 were working, 15 were seeking work, 8 were unemployed, and 19 were categorized as other. The median number of consultations was 1 (1,11). The content of consultations was the social security system in 44 cases (37.6%) job seeking in 24 cases (20.5%), how to inform the workplace in 14 cases (12%), and workplace environment adjustment in 13 cases (11.1%). CONCLUSIONS: We conducted a survey on the actual status of employment consultation in a cancer center hospital. The majority of consultations were completed in one session. In terms of the content of consultations, there was a high need for consultations on the social security system and job seeking. Further study is needed on the characteristics of employment consultations according to employment status and other attributes.

Alginates as food ingredients absorb extra salt in sodium chloride-treated mice.

Many patients with impaired renal function undergoing dialysis are subject to severe dietary restrictions. Especially overdose of salt is related to crisis of their life, so their meals are basically salt-free or low salt. Therefore, their quality of life is declined due to their yearning for salty taste. In the present study, we searched new salt-adsorbing food materials in dietary fibers to develop food ingredients preventing salt-sensitive hypertension and kidney dysfunction. As a result, calcium alginate and ammonium alginate possessed sodium-binding capacity without releasing potassium which causes a problem in chronic kidney injury. Furthermore, the administration of those fibers inhibited blood NaCl concentration and induced NaCl excretion in mice model. Therefore, calcium alginate and ammonium alginate are new candidate materials as salt-adsorbing materials, thus indicating that the health foods and/or health supplements containing those fibers may be a potentially new tool for prevention of salt-sensitive hypertension and kidney dysfunction.

AgSbF6-promoted cycloaddition reaction of 2-trifluoromethyl-N-tosylaziridine with aldehydes.

2-Trifluoromethyl-N-tosylaziridine reacted with various aldehydes in the presence of a catalytic amount of AgSbF(6) to provide the corresponding cis-4-trifluoromethyl-2-substituted-N-tosyl-1,3-oxazolidines with excellent regio- and stereoselectivity.

Preparation and reactions of (beta-trifluoromethyl)vinyl sulfonium salt.

(Beta-trifluoromethyl)vinyl sulfonium salt as a novel three-carbon fluorinated building block was conveniently prepared from easily available (beta-trifluoromethyl)vinyl sulfide and diphenyl iodonium salt in excellent yield. This easily handled crystalline reagent displayed two types of useful transformation involving aziridination and vinylation to afford the corresponding trifluoromethylated compounds in excellent yields.

Supramolecular insulating networks sheathing conducting nanowires based on organic radical cations.

Six materials, (EDT-TTF)(4)BrI(2)(TIE)(5) (1, where EDT-TTF = ethylenedithiotetrathiafulvalene and TIE = tetraiodoethylene), (EDST)(4)I(3)(TIE)(5) (2, where EDST = ethylenedithiodiselenadithiafulvalene), (MDT-TTF)(4)BrI(2)(TIE)(5) (3, where MDT-TTF = methylenedithiotetrathiafulvalene), (HMTSF)(2)Cl(2)(TIE)(3) (4, where HMTSF = hexamethylenetetraselenafulvalene), (PT)(2)Cl(DFBIB)(2) (5, where PT = bis(propylenedithio)tetrathiafulvalene and DFBIB = 1,4-difluoro-2,5-bis(iodoethynyl)benzene), and (TSF)Cl(HFTIEB) (6, where TSF = tetraselenafulvalene and HFTIEB = 1,1',3,3',5,5'-hexafluoro-2,2',4,4'-tris(iodoethynyl)-biphenyl), consisting of conducting nanowires were obtained by galvanostatic oxidation of the donor molecules in the presence of the corresponding halide anions and iodine-containing neutral molecules. We report their characterizations using single-crystal crystallography, electrical resistance measurements, and electron spin resonance. The structures are built on stacks of planar cations of the donors that are isolated electrically by an insulating network consisting of supramolecular assemblies of the halide anions and neutral molecules held together by a halogen bond. The size and shape as well as the orientation (tilt) of the donors are matched by the self-organization of the insulating sheaths in all cases, providing a pea-in-a-pod example in the field of supramolecular chemistry. The observed resistivities, resistivity anisotropies, and electron spin resonance behaviors of these salts are analyzed by tight-binding band calculations and resistance-array modeling. Crystal 6 with insulating layer of 1 nm thickness exhibits 8 orders of magnitude anisotropy in its resistivity, indicating high potential of the supramolecular network as sheathing material. The observation of such networks leads us to propose a roadmap for future development toward multidimensional memory devices.

[Posterior interosseous nerve palsy in a man in a lateral position for laparoscopic adrenalectomy--a case report].

A 51-year-old man with aldosteronism underwent laparoscopic left adrenalectomy. Anesthesia was induced with fentanyl 0.1 mg, propofol 140 mg and vecuronium 7 mg. Following endotracheal intubation, he was placed in a right lateral position with extension of his left side, and fixed with the Magic Bed. Canulation of the right radial artery was smoothly performed. Anesthesia was maintained with sevoflurane and thoracic epidural anesthesia (mepivacaine and ropivacaine). The operation lasted for 270 minutes and was uneventful. A few hours after surgery, he complained of inability to extend his right fingers without any sensory loss, and the local oppressive pain on his right forearm. Neurological examination revealed a posterior interosseous palsy. Symptoms improved gradually and disappeared completely in two months with the administration of vitamin B12 and physical therapy. Postoperative reproduction of the positioning of this case disclosed that the edge of the Magic Bed might potentially compress the posterior interosseous nerve at the point where the nerve is bifurcated from the radial nerve and travels within the supinator muscle going into the muscle again. This case indicated that we must be careful of nerve injuries due to devices used to maintain the patient in lateral position.

[Heparin resistance during cardiopulmonary bypass].

A 74-year-old man was scheduled for coronary artery bypass graft surgery with cardiopulmonary bypass. After intravenous heparin (200 U.kg-1), the activated clotting time (ACT) increased from 124 to 436 sec. However, it decreased to 128 sec immediately after cardiopulmonary bypass. The bypass was discontinued because the addition of heparin (200 U.kg-1) proved heparin resistance. The coronary artery bypass procedure was completed uneventfully without cardiopulmonary bypass. Several recent articles have reported that heparin resistance was corrected with antithrombin III concentrates, fresh frozen plasma, or argatroban. In this case, these drugs could not be used because the mechanism of heparin resistance remains uncertain. Thus, the off-pump technique is useful for unknown heparin resistance.

[Anesthetic management for cerebral aneurysm surgery in a patient with aortitis syndrome accompanied by lung edema].

A 48-year-old woman with aortitis syndrome underwent clipping of dissecting aneurysm of the left posterior inferior cerebellar artery following subarachnoid hemorrhage. Preoperative echocardiography demonstrated moderate aortic regurgitation and pulmonary hypertension. Intravenous infusion (1900 ml.day-1) was performed to avoid cerebral vasospasm, but the patient developed lung edema. She received delayed surgical treatment after the improvement of lung symptoms. Anesthesia was induced with fentanyl (0.1 mg), propofol (90 mg) and vecuronium (6 mg). Radial arterial flow was judged to be insufficient for cannulation, and a cannulation was therefore performed on the dorsal pedis artery. During induction of anesthesia, there was a significant decrease in the arterial pressure, that required a total of 32 mg of intravenous ephedrine. Following tracheal intubation, a central venous catheter was inserted and dopamine was continuously administered. The patient was positioned in the park bench position. We thought that the placement of the introducer for Swan-Ganz catheter was difficult under the position and Swan-Ganz catheter was not inserted. Anesthesia was maintained with sevoflurane, air, and oxygen. We continuously monitored the central venous pressure as an indicator of fluid balance. In this case, we monitored dorsal pedis arterial pressure directly, which might not be sufficiently reliable to predict the decrease in cerebral blood flow.

[Successful control of rapid heart rate in a patient with atrial fibrillation by continuous intravenous administration of landiolol hydrochloride].

A 79-year-old man with atrial fibrillation underwent total pharyngolaryngectomy and free flap reconstruction for hypolaryngeal cancer under general anesthesia. He developed tachyarrhythmia with ST depression and inverted T wave. The treatment including sufficient fluid therapy, continuous administration of vasodilator and intravenous digoxin failed to control the abnormalities. Then landiolol hydrochloride, a new cardioselective ultra-short acting beta-blocker, was continuously administered. Despite the relatively low doses with 1 min loading infusion at 0.04 mg.kg-1.min-1 and continuous infusion at 0.016 mg.kg1.min-1, rapid control of heart rate occurred in a few minutes and inverted T waves were normalized in fifteen minutes. There was no significant change of peripheral blood pressure. The present case suggests that landiolol hydrochloride is effective in controlling heart rate in a patient with atrial fibrillation and that the optimal dose should be carefully evaluated for each case.
