RESUMO

BACKGROUND: Japanese larch (Larix kaempferi) is an economically important deciduous conifer species that grows in cool-temperate forests and is endemic to Japan. Kuril larch (L. gmelinii var. japonica) is a variety of Dahurian larch that is naturally distributed in the Kuril Islands and Sakhalin. The hybrid larch (L. gmelinii var. japonica × L. kaempferi) exhibits heterosis, which manifests as rapid juvenile growth and high resistance to vole grazing. Since these superior characteristics have been valued by forestry managers, the hybrid larch is one of the most important plantation species in Hokkaido. To accelerate molecular breeding in these species, we collected and compared full-length cDNA isoforms (Iso-Seq) and RNA-Seq short-read, and merged them to construct candidate gene as reference for both Larix species. To validate the results, candidate protein-coding genes (ORFs) related to some flowering signal-related genes ​were screened from the reference sequences, and the phylogenetic relationship with closely related species was elucidated. RESULTS: Using the isoform sequencing of PacBio RS ll and the de novo assembly of RNA-Seq short-read sequences, we identified 50,690 and 38,684 ORFs in Japanese larch and Kuril larch, respectively. BUSCO completeness values were 90.5% and 92.1% in the Japanese and Kuril larches, respectively. After comparing the collected ORFs from the two larch species, a total of 19,813 clusters, comprising 22,571 Japanese larch ORFs and 22,667 Kuril larch ORFs, were contained in the intersection of the Venn diagram. In addition, we screened several ORFs related to flowering signals (SUPPRESSER OF OVEREXPRESSION OF CO1: SOC1, LEAFY: LFY, FLOWERING Locus T: FT, CONSTANCE: CO) from both reference sequences, and very similar found in other species. CONCLUSIONS: The collected ORFs will be useful as reference sequences for molecular breeding of Japanese and Kuril larches, and also for clarifying the evolution of the conifer genome and investigating functional genomics.

RESUMO

Candidemia is a life-threatening fungal infection among patients undergoing long-term intravenous catheterization, hematopoietic stem cell transplantation, or immunosuppressive therapy, as well as patients with severe immunodeficiency or cancer. Endophthalmitis is a rare but severe form of ocular inflammation caused by infection of the intraocular cavity, which can lead to irreversible visual loss if not treated properly and promptly. The initial manifestation typically involves chorioretinitis, which requires early diagnosis and appropriate treatment. Candida guilliermondii is a non-Candida albicans yeast species; its frequency of detection in Japan has increased in recent years, and many drug-resistant and less-chorioretinitis-related strains are known. Here, we describe a 17-year-old girl with an eating disorder who exhibited chorioretinitis because of catheter-related bloodstream infection (CRBSI) caused by C. guilliermondii. The patient was hospitalized with severe weight loss, and she was presumed to develop candidemia because of immunosuppression during central parenteral nutrition therapy with a peripherally inserted central catheter. After onset of CRBSI, the catheter was immediately removed. Antifungal therapy was modified following fundus examination, fungal species confirmation, and drug sensitivity confirmation; thus, the patient recovered without long-term complications. To the best of our knowledge, this is the first report of C. guilliermondii-induced chorioretinitis in a patient with an eating disorder. Prolonged malnutrition and immunosuppression during nutritional therapy create a risk of candidemia in patients with eating disorders. After the onset of CRBSI, early administration and appropriate use of antifungal agents, with respect to specific ocular complications, are important for reduction of both mortality and ocular complications.

RESUMO

BACKGROUND: Treatment of adolescent eating disorder requires early improvement of nutritional status. Central venous hyperalimentation is used but catheter-related bloodstream infection (CRBSI) is a complication. There have been no reports examining risk factors for CRSBI in eating disorders. METHODS: The subjects were 51 patients who received nutritional therapy with the use of a peripherally inserted central catheter (PICC) from January 2012 to December 2019. The courses of weight and white blood cell (WBC) count were examined retrospectively during nutritional therapy. Onset factors for CRBSI were determined and a case series of CRBSI caused by Candida parapsilosis is presented. RESULTS: The day of minimum weight occurred on or before day 7 in 37 of the 51 patients, and this day was preceded by the day with the lowest WBC at a significant rate. The minimum weight day was significantly delayed in CRSBI cases compared with non-CRBSI cases (P = 0.02). In the case series of CRBSI caused by C. parapsilosis, the median WBC count before CRBSI decreased to 2,570 (1,680-3,270)/µL at a median of day (12-90) 36. Catheter-related bloodstream infection developed at a median of day (26-133) 38. The PICC was immediately removed and an antifungal drug was started, leading to cure with no after effects in all subjects. CONCLUSIONS: In patients with an eating disorder treated with nutritional therapy using a PICC, prolonged resistance to weight gain became a risk factor for developing CRBSI. White blood cell counts recover after weight gain, which suggests that there is a risk of developing CRBSI, even with improved appetite and weight gain.

RESUMO

The genus Bifidobacterium is well known to have beneficial health effects. We discovered that quercetin and related polyphenols enhanced the secretion of anti-inflammatory substances by Bifidobacterium adolescentis. This study investigated characteristics of the anti-inflammatory substances secreted by B. adolescentis. The culture supernatant of B. adolescentis with quercetin reduced the levels of inflammatory mediators in activated macrophages. Spontaneous quercetin degradant failed to increase anti-inflammatory activity, while the enhancement of anti-inflammatory activity by quercetin was sustained after washout of quercetin. Physicochemical treatment of the culture supernatant indicated that its bioactive substances may be heat-stable, non-phenolic, and acidic biomolecules with molecular weights less than 3 kDa. Acetate and lactate have little or no effect on nitric oxide production. Taken together, the anti-inflammatory substances secreted by B. adolescentis may be small molecules but not short chain fatty acids. In agreement with these findings, stearic acid was tentatively identified as a bioactive candidate compound.

RESUMO

High-flow bypass followed by ligation of the internal carotid artery (ICA) is an effective treatment, but the impact of abrupt occlusion of the ICA is unpredictable, especially on postoperative cognitive function. The present study evaluated the clinical results as well as cognitive performances after high-flow bypass using radial artery graft (RAG) with supportive superficial temporal artery (STA)-middle cerebral artery (MCA) bypass, followed by ICA ligation. Ten consecutive patients underwent high-flow bypass surgery for large or giant ICA aneurysms of cavernous or cervical portion. Demographics, clinical information, magnetic resonance (MR) imaging, computed tomography, digital subtraction angiography (DSA), intraoperative somatosensory evoked potentials, neuropsychological examinations including the Wechsler Adult Intelligence Scale-Third Edition and the Wechsler Memory Scale-Revised (WMS-R), and follow-up data were analyzed. The aneurysm was located on the cavernous segment in eight cases and cervical segment in two cases, and mean aneurysm size was 27.9 mm. Postoperative DSA demonstrated robust bypass flow from the external carotid artery to MCA via the RAG, and no anterograde flow into the aneurysm. No patient showed new symptoms after the operation. Follow-up clinical study and MR imaging were performed in nine patients and showed no additional ischemic lesion compared with preoperative imaging. Seven patients completed neuropsychological examinations before and after surgery. All postoperative scores except WMS-R composite memory score slightly improved. High-flow bypass followed by ICA ligation can achieve good clinical outcomes. Successful high-flow bypass using RAG with supportive STA-MCA bypass and ICA ligation does not adversely affect postoperative cognitive function.

RESUMO

Headache is a major symptom in chronic subdural hematoma (CSDH) patients. However, some CSDH patients do not complain headache although the hematoma is thick with definite midline shift. This clinical study was performed to identify the mechanism of headache in CSDH patients. We compiled clinical data of 1080 surgically treated CSDH patients (711 males and 369 females), and in 54 cases, the pressure of hematoma was measured during burr hole surgery using a glass-stick manometer. Headache was recognized in 22.6% of patients, while nausea or vomit suggesting increased intracranial pressure was detected in only 3.0%. Ophthalmological examination was performed in 238 patients, and papilledema was identified in only one patient (0.4%). The mean age of patients with headache (59.8 ± 16.9 years) was significantly younger than that of those without (75.7 ± 11.2 years) (P < 0.01). In 54 cases, the mean hematoma pressure was not significantly different between patients with (17.1 ± 6.2 mmH2O) and without (18.4 ± 7.2 mmH2O) headache (P > 0.10). Hematoma thickness was significantly greater in patients without headache (P < 0.01), but the ratio of midline shift to hematoma thickness was significantly greater in patients with headache (P < 0.01). In our results, the status of increased intracranial pressure was rare in CSDH patients, and high hematoma pressure was not a cause of headache. Midline shift was the most influenced factor for headache in our study, and based on the results, the authors consider that the potential cause of headache in CSDH might be stretching or twisting of the pain-sensitive meninges and meningeal arteries or veins.

RESUMO

A 60-year-old woman was administered mFOLFOX6 therapy as postoperative adjuvant chemotherapy for fStage III a ascending colon cancer. The patient developed a disorder of consciousness(Japan Coma Scale[JCS]III-200)immediately after the completion of the therapy. Blood ammonia levels were high at 319 mg/dL, and a diagnosis of disturbance of consciousness due to hyperammonemia was made. The patient's state of consciousness improved on the following day as blood ammonia levels decreased due to treatment with branched chain amino acid(BCAA)formulation and oxygen. Two months later, mFOLFOX6 therapy was again administered with strengthening measures for side effects to nausea and vomiting and reducing 5-FU, but the patient again developed a disorder of consciousness(JCS III-200). The 5-FU administration rate was considered as a potential cause of hyperammonemia. Hyperammonemia induced by 5-FU is relatively rare, with a reported incidence of 5-9%; however, caution is required with high dosage regimens of 5-FU that are currently recommended for colorectal cancer therapy because hyperammonemia is an important side effect.

RESUMO

BACKGROUND: Although there is evidence about the beneficial effects of probiotics, their effects on aspirin-induced small bowel injuries have not been well examined. We evaluated the effects of the probiotic Lactobacillus gasseri OLL2716 (LG) on aspirin-induced small intestinal lesions, such as ulcers, erosions, reddened lesions, and bleeding. SUMMARY: This study enrolled 64 patients who received aspirin for more than 1 month and provided written informed consent to be part of the study. The patients received 112 ml of yogurt containing LG or placebo twice daily for 6 weeks. Small bowel injuries were evaluated by capsule endoscopy before and after consuming the yogurt. The effect of LG on patient symptoms was also assessed using the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) and Gastrointestinal Symptom Rating Scale (GSRS) questionnaires before and after 6 weeks of treatment. There was no significant difference in any baseline characteristics and the number of small bowel mucosal breaks between the 2 groups. In contrast with the placebo group, the LG group had significantly fewer small bowel mucosal breaks and reddened lesions after 6 weeks (p < 0.01). The FSSG and GSRS scores were also significantly improved in the LG group but not in the placebo group. Key Messages: This double-blind, placebo-controlled study found that LG may be useful in reducing aspirin-induced small bowel injuries and in mitigating gastrointestinal symptoms.

RESUMO

This video demonstrates a surgical technique of resecting dorsum sellae meningioma using a combined interhemispheric translamina terminalis approach and pterional approach with clinoidectomy. The tumor, 5 cm in maximum diameter, originated from the dorsum sellae, compressed the third ventricle and the midbrain, and displaced the pituitary stalk ventrally. Feeding arteries of the tumor were bilateral meningohypophyseal trunks, mainly from the right side. The authors performed devascularization of the tumor via a right pterional approach following frontotemporal craniotomy, and debulking of the tumor via an interhemispheric translamina terminalis approach following bifrontal craniotomy. These procedures with two separate craniotomies enabled safe and effective resection of the tumor. The video can be found here: https://youtu.be/DEnKOC5zQ_M .

RESUMO

BACKGROUND: The frontal bridging vein, which is the venous drainage route of the frontal cortex into the superior sagittal sinus (SSS), sometimes poses an obstacle in the anterior interhemispheric approach during surgery for anterior cerebral artery aneurysms. Although severe complications including venous infarction or edema due to damage to the bridging vein are well known, only a few reports have discussed how to avoid venous injury when we must sacrifice the bridging vein to obtain an appropriate surgical field. This report describes a microvascular technique performed in two patients who underwent rerouting of the bridging vein to obtain an appropriate anterior interhemispheric surgical corridor to treat a ruptured anterior cerebral artery aneurysm. The hindering bridging vein was resected from the entrance to the SSS and anastomosed toward the adjacent cortical vein. METHODS: A 65-year-old male and a 43-year-old male were admitted to our hospital for sudden headache. Computed tomography, magnetic resonance angiogram, or digital subtraction angiography demonstrated a subarachnoid hemorrhage and an anterior cerebral artery aneurysm in both patients. In both cases, a relatively robust bridging vein, which appeared problematic to sacrifice, was draining into the SSS, resulting in a limited surgical corridor. Thus, we performed cortical vein reconstruction, and the aneurysms were successfully clipped under a wider surgical view. RESULTS: We confirmed completed clipping without postoperative venous complications. One patient demonstrated patency of reconstructed venous flow by digital subtraction angiography. No apparent cognitive impairment was seen in either patient. CONCLUSIONS: This technique may be useful for obtaining an appropriate surgical corridor when the frontal bridging vein may be damaged.

RESUMO

Direct clipping of giant partially thrombosed intracranial internal carotid artery (ICA) aneurysms is challenging, especially when important perforating arteries are involved. Proximal occlusion with bypass represents a possible alternative approach. An 80-year-old female presented with worsening visual acuity and severe headache caused by partially thrombosed giant (38 mm in diameter) aneurysms of the right ICA, suggestive of impending rupture. Direct clipping in conjunction with temporary occlusion of the lesion involving the anterior choroidal artery (AChA) was considered too risky. Thus, we sequestrated the ipsilateral ICA flow into a low-flow and a high-flow system using two external carotid artery (ECA)-ICA bypasses and one in situ bypass with cervical ICA ligation. As a result, the low-flow system by the superficial temporal artery-middle cerebral artery (MCA) bypass perfused mainly the proximal MCA lesions and aneurysm, whereas the high-flow system by ECA-radial artery-M2 bypass exclusively supplied the residual distal MCA area. This tailored flow sequestration successfully interrupted intra-aneurysmal flow and accelerated near-complete thrombosis of the aneurysm while preserving the AChA and avoiding any significant neurological deterioration. We conclude that this method is effective for the management of giant partially thrombosed aneurysms of the ICA, especially when direct clipping is difficult.

RESUMO

Clinical results as well as cognitive performances after extracranial to intracranial (EC-IC) bypass in conjunction with contralateral carotid endarterectomy (CEA) are poorly understood. Data from 14 patients who underwent unilateral EC-IC bypass for atherosclerotic internal carotid artery (ICA)/middle cerebral artery (MCA) steno-occlusive disease in conjunction with CEA for contralateral cervical carotid stenosis were retrospectively reviewed. Postoperative results were evaluated by MRI imagings. Nine patients also underwent neuropsychological examinations (NPEs), including assessment by the Wechsler Adult Intelligence Scale-Third Edition and the Wechsler Memory Scale-Revised (WMS-R) before and about 6 months after bilateral surgeries. Postoperative MRI follow-up (median, 8 months; interquartile range, 7-8 months) confirmed successful bypass in all patients, with no additional ischemic lesions on T2WI when compared with preoperative imaging. Further, MRA showed patent bypass and contralateral smooth patency at CEA portion in all patients. In the group rate analysis, all five postoperative NPE scores (Verbal IQ, Performance IQ, WMS-memory, WMS-attention, and Average scores of all those four scores) were improved relative to preoperative NPE scores. Performance IQ and Average score improvements were statistically significant. Clinical results after EC-IC bypass in conjunction with contralateral CEA were feasible. Based on the group rate analysis, we conclude that successful unilateral EC-IC bypass and contralateral carotid endarterectomy does not adversely affect postoperative cognitive function.

RESUMO

The authors demonstrate an interhemispheric transchoroidal approach for third ventricular teratoma resection. Interhemispheric dissection exposed the corpus callosum at a length of about 2 cm. A callosotomy was made to enter into the right lateral ventricle. After septal vein ligation, dissection was made of the space between the right fornix and right internal cerebral vein (ICV); thus bilateral fornix and left ICV would be retracted to the left; right choroid plexus, right ICV to the right. By this transchoroidal approach, the foramen of Monro was extended posteriorly, providing enough of a surgical corridor to resect a posteriorly located third ventricular tumor.

RESUMO

BACKGROUND: The mechanisms underlying post-extracranial to intracranial (EC-IC) bypass neurocognitive changes are poorly understood. METHODS: Data from 55 patients who underwent a unilateral EC-IC bypass for atherosclerotic internal carotid artery (ICA)/middle cerebral artery (MCA) steno-occlusive disease were retrospectively evaluated. These patients underwent neuropsychological examinations (NPEs), including assessment by the Wechsler Adult Intelligence Scale-Third Edition and Wechsler Memory Scale-Revised (WMS-R) before and 6 months after EC-IC bypass. Results of NPEs were converted into Z-scores from which preoperative cognitive composite scores (CSpre) and postoperative cognitive composite scores (CSpost) were obtained. The association between the change of composite score between pre- and postoperative NPEs (CSpost-pre = CS post - CS pre) and various variables were assessed. These latter variables included occluded artery (ICA or MCA), preexisting ischemic lesion as verified in preoperative T2WI, robust bypass patency as verified by MRA performed approximately 6 months postoperatively, and postoperative transient neurological symptoms and/or postoperative chronic subdural hematoma (CSDH), both of which were dichotomized as postoperative events. RESULTS: Postoperative MRI follow-up (median, 6 months; interquartile range, 5-8 months) confirmed successful bypasses in all patients, with no additional ischemic lesions on T2WI when compared with preoperative imaging. Further, MRA showed patent bypasses in all patients. A nearly statistically significant CS post-pre decrease was observed in patients with postoperative events when compared with those without postoperative events (-0.158 vs. 0.039; p = 0.069). A multiple regression model predicting CSpost-pre was performed. After controlling for occluded arteries, postoperative events were identified as an independent predictor of a decline in CSpost-pre (p = 0.044). In the group rate analysis, three of four postoperative NPE scores (Performance IQ, WMS-memory, WMS-attention) were significantly improved relative to preoperative NPE scores. CONCLUSIONS: Postoperative transient neurological symptoms and/or CSDH might play a significant role in the subtle decline in cognition following an EC-IC bypass. However, this detrimental effect was small, and based on the group rate analysis, we concluded that a successful unilateral EC-IC bypass does not adversely affect postoperative cognitive function.

RESUMO

Probiotics have been shown to improve the condition of not only the human gastrointestinal tract but also the entire body. We found that quercetin enhances the anti-inflammatory activity of Bifidobacterium adolescentis, which is abundant in human intestines. Here, we assessed whether certain phytochemicals could enhance the anti-inflammatory activity of B. adolescentis. Bifidobacteria were anaerobically cultured with phytochemicals for 3 h, and the anti-inflammatory activity of the supernatants was estimated by testing their ability to inhibit nitric oxide (NO) production by lipopolysaccharide-stimulated RAW264 macrophages. Of the 55 phytochemicals tested, phloretin, (+)-taxifolin, and (-)-epigallocatechin gallate as well as quercetin-3-O-glucoside and quercetin-4'-O-glucoside were similar to quercetin in promoting NO suppression by B. adolescentis. In addition, the phytochemicals excluding quercetin increased the concentrations of lactic and acetic acids in the co-culture supernatants. These results suggest that some phytochemicals may activate the anti-inflammatory function of B. adolescentis.

RESUMO

The aim of this study was to assess the efficacy and safety of surgical embolectomy for internal carotid artery terminus (ICA-T) occlusion. Twenty-five consecutive patients with acute ischemic stroke attributed to embolic ICA-T occlusion who underwent surgical embolectomy were retrospectively reviewed. Twenty-four patients were examined based on magnetic resonance imaging, with one patient included based on a computed tomography scan. Recanalization rate, recanalization time, complications, National Institutes of Health Stroke Scale (NIHSS) score improvement at 1 month, and modified Rankin Scale (mRS) at 3 months were evaluated. Final recanalization status was Thrombolysis in Myocardial Infarction (TIMI) 3 in 24 patients (96 %). Median recanalization time from symptom onset and from start of surgery was 281 and 79 min, respectively. Two patients (8 %) had major hemorrhagic complications related to surgery. Seventeen patients (68 %) demonstrated NIHSS score improvement of more than 10 points at 1 month. At 3 months, eight patients (32 %) were mRS 0-2, five patients (20 %) were mRS 3, and three patients (12 %) had died. Surgical embolectomy for ICA-T occlusion demonstrated a high complete recanalization rate and should be reconsidered as an additional therapeutic strategy to overcome this devastating situation.

RESUMO

The authors show a surgical technique of trapping/resection of ruptured dominant vertebral artery aneurysm in conjunction with reconstruction of vertebral artery by V3-radial artery (RA) graft-V4 bypass through suboccipital craniotomy and far lateral approach. Step by step muscle dissection in posterior fossa enable fine exposure of occipital artery for possible OA-PICA bypass and V3 portion of vertebral artery. Extradural drilling of posterior one-third condyle and condylar fossa facilitate exposure of triangular surgical corridor made by medulla, spinal root of 11th nerve and lower cranial nerves, and thus enabling aneurismal resection and RA-V4 anastomosis.

RESUMO

This video demonstrates combined two separate craniotomies for two difficult unruptured cerebral aneurysms. The anterior communicating artery (ACOM) aneurysm existed at a high position, projected posteriorly, and thus necessitated an interhemispheric approach. Left middle cerebral artery (MCA) aneurysm with complex figure was treated through a separate pterional approach. Meticulous micro-cisternal opening under high magnification enabled safe and effective exposure of both aneurysms with minimal brain retraction, which alleviated brain damage as shown in postoperative images.

RESUMO

The authors show a surgical technique of clipping in conjunction with superficial temporal artery (STA)-middle cerebral artery (MCA) bypass to treat unruptured anterior communicating artery (AcomA) aneurysm associated with unilateral MCA occlusion. First, through MCA occlusion side, fronto-temporal craniotomy, extra-dural drilling of lesser sphenoid wing, and followed by wide exposure of Sylvian fissure, STA-MCA bypass was performed. Then, through trans-Sylvian, fronto-basal, and lateral trajectory, interhemispheric fissure was dissected from the base, which enabled good exposure and clipping of high positioned AcomA aneurysm.
