RESUMEN

STUDY DESIGN: A retrospective cohort study. PURPOSE: To investigate the outcomes of balloon kyphoplasty (BKP) for vertebral compression fractures (VCFs) at the distal end or adjacent vertebra of the fused segments in patients with diffuse idiopathic skeletal hyperostosis (DISH). OVERVIEW OF LITERATURE: Vertebral fractures in the midportion of the fused segments in patients with DISH are generally unstable; thus, immobilization is recommended. However, VCFs classified as type A in the AO classification are observed at the distal end and adjacent vertebra of the fused segments, and treatment strategies for VCFs associated with DISH remain controversial. METHODS: The outcomes of 72 patients who underwent BKP for VCFs between 2015 and 2021 were retrospectively investigated. Patients with DISH were assigned to group D (n=21), whereas those without DISH were assigned to group ND (n=51). Back pain, incidence of subsequent adjacent fractures, reoperation rates, and local kyphosis were statistically analyzed. RESULTS: VCFs in group D occurred at the distal end or adjacent vertebra of the fused segments, and no fractures occurred in the midportion of the fused segment. Back pain improved in both groups, with no significant differences between them. Subsequent adjacent fractures were observed in three of the 21 patients in group D and 11 of the 51 patients in group ND, with no significant difference between them. Reoperation was performed in one patient each in groups D and ND, with no significant difference between the groups. Postoperatively, local kyphosis progressed significantly in group D. CONCLUSIONS: Although local kyphosis is more advanced in patients with DISH, BKP is effective for VCFs at the distal end or adjacent vertebra of the fused segments and may be useful in older patients with high complication rates.

RESUMEN

STUDY DESIGN: This study adopted a retrospective cohort study design. PURPOSE: This study aimed to clarify the influence of diffuse idiopathic skeletal hyperostosis (DISH) on bone fusion after transforaminal lumbar interbody fusion (TLIF). OVERVIEW OF LITERATURE: The negative effects of DISH on lumbar degenerative diseases have been reported, and DISH may be involved in the onset and severity of lumbar spinal canal stenosis. Patients with DISH have significantly more reoperations after posterior lumbar fusion, including TLIF. However, the effects of DISH on bone fusion after TLIF have not been reported. METHODS: The medical records of patients with intervertebral TLIF from 2012 to 2018 were retrospectively examined. The patients were divided into those with fusion and those with pseudoarthrosis, and the following data were compared: age, sex, DISH, diabetes mellitus, smoking, drinking, albumin levels, body mass index ≥30 kg/m2, and L5/S fixation. Statistical analyses were performed using regression models. RESULTS: In this study, 180 patients (78.6%) had fusion and 49 patients (21.4%) had pseudoarthrosis. The number of patients with DISH was significantly higher in the pseudoarthrosis group than in the fusion group (36.7% and 21.7%, respectively; univariate p=0.031, multivariate p =0.019). No significant differences in age, sex, diabetes mellitus, smoking, drinking, albumin levels, body mass index ≥30 kg/m2, and L5/S fixation were observed between the two groups. The risk factors for bone fusion were statistically analyzed in 57 patients with DISH. DISH with a caudal end below Th11 was an independent risk factor for pseudoarthrosis (univariate p=0.011, multivariate p=0.033). CONCLUSIONS: DISH is an independent risk factor for pseudoarthrosis after one intervertebral TLIF, and DISH with a caudal end below Th11 is associated with a higher risk of pseudoarthrosis than DISH without a caudal end below Th11.

RESUMEN

AIMS: This study aimed to investigate the differences in the prognosis of older patients who received home care or hospitalized care to treat acute fever in Japan. METHODS: This prospective case-control study screened 192 registered acutely pyrexic older patients who received home care at 10 medical institutions in Japan, and enrolled 15 and 30 patients who were treated in the hospital (hospitalized group) and at home (home-care group), respectively, matched for fever and the physical conditions before fever onset. Intergroup differences in the 90-day mortality from fever onset and changes in patients' disability and dementia from the pre-fever to 90 days post-fever onset were determined. RESULTS: No significant intergroup difference in the 90-day mortality rate was detected (26.7% vs 13.3% for hospitalized and home-care groups, respectively, P = 0.41). Disability tended to worsen in the hospitalized group compared with the home-care group (54.5% vs 23.1%, respectively, P = 0.06), whereas dementia significantly worsened in the hospitalized group compared with the home-care group (45.5% vs 3.8%, respectively, P = 0.02). CONCLUSIONS: Home care confers a better prognosis for treating acute fever in older people whose daily functions have deteriorated enough to necessitate regular home care. This study assists those people in making informed choices about where to receive treatment for acute fever. Geriatr Gerontol Int 2023; 23: 355-361.

RESUMEN

Intending to obtain scientific evidence to use in developing indicators for evaluating the quality of home care, we surveyed doctors, nurses, and other home care professionals to determine the points they consider to be essential in evaluating home care. We investigated all 901 clinics registered to the National Association of Medical Institutions Supporting Home Care and a random sample of 600 Visiting Nurse Service stations registered to the National Association for Visiting Nurse Service in Japan. A total of 539 questionnaire responses were received (response rate: 35.9%). In this study, a factor analysis revealed four factors to be considered when evaluating the quality of home care: (1) patients' and family members' level of satisfaction, (2) home care process, (3) structure of home care, and (4) medical outcomes. The factor of the satisfaction of patients and family members identified in the present study was not considered in previous studies for evaluating the quality of care in Japan. Satisfaction is the point of difference in goals between hospital-based care and home care, and it requires different measurement indicators. Home care professionals expect to help relieve the physical and psychological burden felt by the patient and their family. Thus, on the evaluation indicators of quality of home care, their perspectives from the present study are valuable.

RESUMEN

AIM: Nurses have difficulty assessing the type of constipation by ordinal assessment methods and may therefore struggle to select an appropriate defecation care. Although previous studies described the safety and effectiveness of defecation care based on ultrasonographic observations in the colorectum, no standardized educational program has been established. This study aimed to determine the feasibility of the constipation point-of-care ultrasound (POCUS) educational program regarding the use of ultrasonography as an assessment tool to determine different types of constipation. METHODS: This descriptive study was conducted for visiting nurses working in Japan. The constipation POCUS educational program that nurses can learn in as short as 7 days comprised four elements: E-learning, a hands-on seminar, self-learning, and objective structured clinical examinations (OSCEs). The nurses were asked to complete a questionnaire regarding the education materials. OSCEs were used to assess the participants' skills in assessing patients based on the use of ultrasound observation in the colorectum. RESULTS: Of the 44 participants who enrolled, 40 were able to complete the program. All the 40 participants (100.0%) who took the OSCEs were able to pass at the first attempt. Moreover, 94.9% of the trainees indicated that this program was able to cover the content necessary to use ultrasonography in home care settings. CONCLUSIONS: The results of this study suggest that the 7-day constipation POCUS educational program provided trainees with a foundational knowledge and skills to observe fecal retention in the colorectum. Thus, further educational program enhancements and clinical skill evaluations are needed to maximize the program's effectiveness in the future.

RESUMEN

AIM: The present study aimed to analyze the use of machine learning in ultrasound (US)-based fecal retention assessment. METHODS: The accuracy of deep learning techniques and conventional US methods for the evaluation of fecal properties was compared. The presence or absence of rectal feces was analyzed in 42 patients. Eleven patients without rectal fecal retention on US images were excluded from the analysis; thus, fecal properties were analyzed in 31 patients. Deep learning was used to classify the transverse US images into three types: absence of feces, hyperechoic area, and strong hyperechoic area in the rectum. RESULTS: Of the 42 patients, 31 tested positive for the presence of rectal feces, zero were false positive, zero were false negative, and 11 were negative, indicating a sensitivity of 100% and a specificity of 100% for the detection of rectal feces in the rectum. Of the 31 positive patients, 14 had hard stools and 17 had other types. Hard stool was detected by US findings in 100% of the patients (14/14), whereas deep learning-based classification detected hard stool in 85.7% of the patients (12/14). Other stool types were detected by US findings in 88.2% of the patients (15/17), while deep learning-based classification also detected other stool types in 88.2% of the patients (15/17). CONCLUSIONS: The results showed that US findings and deep learning-based classification can detect rectal fecal retention in older adult patients and distinguish between the types of fecal retention.

RESUMEN

AIM: To examine whether the outcomes of fever treatment through home care differ from those through hospitalized care for older people who regularly receive home care in Japan. METHODS: A retrospective survey of medical record-based data for 679 older people who regularly received home care provided by a clinic in Japan. From these data, 61 fever cases (21 cases treated in the hospital and 40 treated at home and assigned to the hospitalized and home-care groups, respectively) were selected for analysis through a matching process. We compared the two groups in terms of mortality rate at 90 days after fever onset, and concerning changes in respective ranks for "Degree of Independent Living for the Elderly with Disability" and "Degree of Independent Living for the Elderly with Dementia" from immediately before fever onset to 90 days after fever onset. RESULTS: The mortality rate tended to be higher in the hospitalized group than in the home-care group (33% vs. 13%, respectively, P = 0.05). The hospitalized group also had a higher proportion of patients whose disability had worsened (43% vs. 23%, respectively, P = 0.16) and a significantly higher proportion of patients whose dementia had worsened (29% vs. 6%, respectively, P = 0.03). CONCLUSIONS: Our findings suggest that home care is more effective than hospitalized care for treating fever in older people who regularly receive home care in Japan, as it leads to lower mortality and better maintenance of activities of daily living capabilities.

RESUMEN

AIM: To verify the efficacy of defecation care based on handheld ultrasonographic observations for functional constipation by visiting nurses skilled in bowel ultrasonography. METHODS: Home-care patients with suspected functional constipation receiving nursing visits were recruited in this multiple-baseline, single-case experiment with intervention points shifted by 1 week. A total of 15 older adults were categorized into 3-, 4-, 5- or 6-week intervention phases. Ultrasonographic observations of fecal retention in the colorectum and defecation care based on observations during the ordinal physical assessment were reviewed. Tau-U was used for confirming the efficacy of the intervention by measuring the number of non-artificial and artificial defecations, as well as hard stools per week, and the amount of non-stimulant and stimulant laxatives, enemas and suppositories per week. For evaluating safety, adverse events, such as bowel obstruction and incontinence-associated dermatitis, were confirmed. RESULTS: No adverse events were observed. Statistical analysis showed that hard stools and artificial defecation reduced, and that their effect sizes were significant (Tau = -0.48, P < 0.01; Tau = -0.53, P < 0.01). Even the amounts of stimulant laxative and glycerin enema reduced, and their effect sizes were significant (Tau = -0.56, P < 0.01; Tau = -0.34, P = 0.04). CONCLUSIONS: Thus, defecation care based on ultrasonographic assessment by nurses in home-care settings is safe and effective for improving constipation symptoms and reducing laxative use.

RESUMEN

BACKGROUND: Although previous studies have demonstrated the ability of ultrasound to detect stool in the colon and rectum, the clinical utility of evaluating constipation via ultrasonic imaging by nurses has not been determined. In this case report, we observed fecal retention, assessed the presence of constipation, and performed defecation care in an older adult patient in a home care setting in a city near the metropolitan area in Japan. CASE: An 85-year-old male with advanced stage prostate cancer and multiple metastases was diagnosed with fecal impaction via digital rectal examination and evaluation of stool consistency. He was managed by regular digital evacuation of stool, but ultrasonic imaging indicated constipation with fecal retention in both the rectum and the colon despite this bowel evacuation program. When faced with this situation, we advocate a bowel management program that considers both intestinal elimination dysfunction and fecal transport dysfunction. Based on ultrasonic imaging, stool consistency was altered by promoting water intake, and we promoted self-defecation by asking the patient to attempt to move his bowels (regardless of cues to defecation) by sitting on the toilet every morning. As a result, the number of weekly enemas and digital dis-impaction episodes decreased while the number of spontaneous defecations increased. CONCLUSION: This case report demonstrated that ultrasonography improved bowel management in this patient with clinically severe chronic constipation.

RESUMEN

OBJECTIVE: Compression of the spinal cord by thoracic ossification of the posterior longitudinal ligament (T-OPLL) often causes severe thoracic myelopathy. Although surgery is the most effective treatment for T-OPLL, problems associated with surgical intervention require resolution because surgical outcomes are not always favorable, and a small number of patients experience deterioration of their neurological status after surgery. The aim of the present study was to examine the surgery-related risk factors contributing to poor clinical outcomes for myelopathy caused by T-OPLL. METHODS: Data were extracted from the records of 55 patients with thoracic myelopathy due to T-OPLL at institutions in the Fukuoka Spine Group. The mean follow-up period was 5.3 years. Surgical outcomes were assessed using the Japanese Orthopaedic Association (JOA) scale. To investigate the definitive factors associated with surgical outcomes, univariate and multivariate regression analyses were performed with several patient-related and surgery-related factors, including preoperative comorbidities, radiological findings, JOA score, surgical methods, surgical outcomes, and complications. RESULTS: Neurological status improved in 33 patients (60.0%) and deteriorated in 10 patients (18.2%) after surgery. The use of instrumentation was significantly associated with an improved outcome. In the comparison of surgical approaches, posterior decompression and fusion resulted in a significantly higher neurological recovery rate than did anterior decompression via a posterior approach and fusion or decompression alone. It was also found that postoperative neurological status was significantly poorer when there were fewer instrumented spinal levels than decompression levels. CSF leakage was a predictable risk factor for deterioration following surgery. CONCLUSIONS: It is important to identify preventable risk factors for poor surgical outcomes for T-OPLL. The findings of the present study suggest that intraoperative CSF leakage and a lower number of instrumented spinal fusion levels than decompression levels were exacerbating factors for the neurological improvement in T-OPLL surgery.

RESUMEN

PURPOSE: Although hypersensitivity reactions (HSRs) to oxaliplatin (L-OHP) therapy are well-documented, few reports have compared different therapies in terms of HSR occurrence. In this study, we compared the frequency and pattern of HSRs to modified FOLFOX6 (mFOLFOX6; 5-fluorouracil, levofolinate calcium and L-OHP infusions) and XELOX (capecitabine and L-OHP) therapies, and sought to identify risk factors associated with HSRs. METHODS: Patients who had received mFOLFOX6 or XELOX chemotherapeutic regimens for unresectable colon or rectal cancer or as adjuvant chemotherapy following colon cancer surgery between April 2012 and August 2015 were included. Potential correlation between treatment modalities (regimen, dosage and route of administration of L-OHP, and injection timing for dexamethasone administration) and HSRs was assessed. RESULTS: Among the 240 patients included in the study, 136 had received mFOLFOX6 therapy and 104 had received XELOX therapy. Although the frequency of HSRs did not differ between the two groups, incidence of HSRs in the first cycle was higher in the XELOX therapy group. Treatment method or cumulative dosage was not identified as a risk factor for HSR; however, the incidence of ≥grade-2 HSR was higher in cases where the cumulative L-OHP dosage was ≥600 mg/m2 and in patients in whom dexamethasone was not co-infused with L-OHP. CONCLUSION: Although HSR rates were comparable among patients treated with mFOLFOX6 and XELOX, HSRs tended to occur more frequently during the first cycle of XELOX therapy as compared to that with mFOLFOX6 therapy. Our findings warrant careful assessment of ≥grade-2 HSRs in patients who are prescribed cumulative L-OHP dosages of ≥600 mg/m2.

RESUMEN

PURPOSE: Pemetrexed (PEM) is an anticancer agent used for the treatment of non-small cell lung cancer, malignant pleural mesothelioma and thymoma. Reportedly, PEM has higher efficacy and safety when used in combination with platinum-based agents. However, there are only few reports on the safety of PEM in patients with an eGFR of ≤45 mL/min. We examined the effect of renal function on the safety of regimens containing PEM. METHODS: We retrospectively reviewed 221 patients with lung cancer, malignant pleural mesothelioma or thymoma who received treatment with a PEM-containing regimen between 2009 and 2014. Subgroup analyses were performed on the basis of pre-treatment renal function: group A [creatinine clearance (CLcr), <45 mL/min]; group B (CLcr, 45-80 mL/min); and group C (CLcr, ≥80 mL/min). For the purpose of this analysis, the lowest documented blood cell counts and haemoglobin levels, the highest levels of serum creatinine, aspartate aminotransferase, alanine aminotransferase and CLcr from the time of initial administration up to prior to the start of second administration were considered. RESULTS: Groups A, B and C had 8, 123 and 90 patients, respectively. The incidence of grade 2 thrombocytopaenia was significantly higher in group A as compared to that in groups B (P < 0.01) and C (P < 0.05). On multivariate analysis, only a CLcr of <45 mL/min was an independent risk factor for thrombocytopaenia of ≥grade 2. CONCLUSION: When administering a PEM-containing regimen, thrombocytopaenia of ≥grade 2 is more likely to develop in patients with a CLcr of <45 mL/min.

RESUMEN

Cancer cells secrete small membranous extracellular vesicles (EVs) into their microenvironment and circulation. Although their potential as cancer biomarkers has been promising, the identification and quantification of EVs in clinical samples remains challenging. Here we describe a sensitive and rapid analytical technique for profiling circulating EVs directly from blood samples of patients with colorectal cancer. EVs are captured by two types of antibodies and are detected by photosensitizer-beads, which enables us to detect cancer-derived EVs without a purification step. We also show that circulating EVs can be used for detection of colorectal cancer using the antigen CD147, which is embedded in cancer-linked EVs. This work describes a new liquid biopsy technique to sensitively detect disease-specific circulating EVs and provides perspectives in translational medicine from the standpoint of diagnosis and therapy.

RESUMEN

PURPOSE: Exosomal microRNAs (miRNAs) have been attracting major interest as potential diagnostic biomarkers of cancer. The aim of this study was to characterize the miRNA profiles of serum exosomes and to identify those that are altered in colorectal cancer (CRC). To evaluate their use as diagnostic biomarkers, the relationship between specific exosomal miRNA levels and pathological changes of patients, including disease stage and tumor resection, was examined. EXPERIMENTAL DESIGN: Microarray analyses of miRNAs in exosome-enriched fractions of serum samples from 88 primary CRC patients and 11 healthy controls were performed. The expression levels of miRNAs in the culture medium of five colon cancer cell lines were also compared with those in the culture medium of a normal colon-derived cell line. The expression profiles of miRNAs that were differentially expressed between CRC and control sample sets were verified using 29 paired samples from post-tumor resection patients. The sensitivities of selected miRNAs as biomarkers of CRC were evaluated and compared with those of known tumor markers (CA19-9 and CEA) using a receiver operating characteristic analysis. The expression levels of selected miRNAs were also validated by quantitative real-time RT-PCR analyses of an independent set of 13 CRC patients. RESULTS: The serum exosomal levels of seven miRNAs (let-7a, miR-1229, miR-1246, miR-150, miR-21, miR-223, and miR-23a) were significantly higher in primary CRC patients, even those with early stage disease, than in healthy controls, and were significantly down-regulated after surgical resection of tumors. These miRNAs were also secreted at significantly higher levels by colon cancer cell lines than by a normal colon-derived cell line. The high sensitivities of the seven selected exosomal miRNAs were confirmed by a receiver operating characteristic analysis. CONCLUSION: Exosomal miRNA signatures appear to mirror pathological changes of CRC patients and several miRNAs are promising biomarkers for non-invasive diagnosis of the disease.

RESUMEN

An 84-year-old woman with heaviness of the right lower extremity had an iliocaval fistula related to a right internal iliac aneurysm. Immediately after deployment of an endovascular device, cardiac arrest occurred because of severely decreased sympathetic activity. After surgery, the patient recovered well and has been followed up with exclusion of the arteriovenous fistula and resolution of the type II endoleak. Endovascular treatment for large arteriovenous fistulas induces rapid closure of the fistula together with restoration of blood supply to the lower extremity. Markedly deactivated sympathetic nerve traffic could result in a critical hemodynamic status in association with endograft deployment.

RESUMEN

We report 3 cases of conjoined nerve root anomalies identified during micro-endoscopic discectomy (MED). Between 2009 and 2010, 61 men and 20 women aged 18 to 84 (mean, 42) years underwent MED for symptomatic lumbar disc herniation of L3-4 (n=1), L4-5 (n=44), and L5-S1 (n=36). Magnetic resonance imaging (MRI), myelogram, and postmyelo computed tomography did not identify the anomalies. All 3 patients were male and had type 2A S1 conjoined nerve roots, with a herniated disc at L5-S1. None of them had any preoperative pseudolocalising neurological signs, but all demonstrated stiffer positive straight leg raise sign and deterioration of the Achilles tendon reflex. Postoperatively, all 3 patients achieved excellent clinical outcomes.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the appropriate condition of use of the fibrin glue plus polyglycolic acid (PGA) sheet combination to obtain the optimal sealing effect. METHODS: 126 consecutive patients underwent video-assisted thoracic surgery (VATS) were divided into groups as follows: fibrin glue sprayed on the PGA sheet placed over the pleural defect (Method I); fibrinogen and thrombin solutions sprayed separately on the PGA sheet soaked in thrombin and placed over the pleural defect after rubbing of fibrinogen solution on the area (Method II); fibrin glue sprayed on the PGA sheet placed over the pleural defect after rubbing of fibrinogen solution on the area (Method III). Method II and Method III were also examined in an animal model. RESULTS: Postoperative air leakage was more effectively prevented by Method III than by the other two methods (p < 0.05). In the experimental study, a significantly higher seal-breaking pressure was obtained for Method III than for Method II (p < 0.05). CONCLUSION: Method III was the most effective for preventing alveolar air leakage.

RESUMEN

BACKGROUND: We aimed to clarify the factors affecting outcomes of home care for patients with malignant diseases. METHODS: Of 607 patients who were treated in 10 clinics specialized in home care between January and December 2007 at Chiba, Fukuoka, Iwate, Kagoshima, Tochigi and Tokyo prefectures across Japan, 346 (57%; 145 men and 201 women) had malignant diseases. We collected information on medical and social backgrounds, details of home care, and its outcomes based on their medical records. RESULTS: Median age of the patients was 77 years (range, 11-102), and 335 patients were economically self-sufficient. Their general condition was poor; advanced cancer (n = 308), performance status of 3-4 (n = 261), and dementia (n = 121). At the beginning of home care, 143 patients and 174 family members expressed their wish to die at home. All the patients received supportive treatments including fluid replacement and oxygenation. Median duration of home care was 47 days (range, 0-2,712). 224 patients died at home. For the remaining 122, home care was terminated due to complications (n = 109), change of attending physicians (n = 8), and others (n = 5). The factors which inhibited the continuity of home care were the non-use of home-visit nursing care (hazard ratio [HR] = 1.78, 95% confidence interval [CI]: 1.05-3.00, p = 0.03), the fact that the patients themselves do not wish to die at home (HR = 1.83, CI: 1.09-3.07, p = 0.02), women (HR = 1.81, CI: 1.11-2.94, p = 0.02), and age (HR = 0.98, CI: 0.97-1.00, p = 0.02). CONCLUSIONS: Continuation of home care is influenced by patients' age, gender, will, and use of home-visit nursing.
