Objective：Independent walking is crucial for critically ill intensive care unit (ICU) patients to return home. We aimed to investigate the characteristics of patients with severe COVID-19 who could walk independently upon discharge.Methods：This study included 26 patients with severe COVID-19 who were admitted to our ICU between April 2020 and September 2023. Patient background, ICU progress, and outcome-related events were compared between the independent and dependent groups.Results：Compared to the dependent group, the independent group had a lower pre-admission clinical frailty scale score (2.0 [2.0-2.5] vs. 3.0 [2.5-3.0]) and shorter time to start standing (seven days [6-9] vs. 13 days [11-17]) and walking (10 days [8-11] vs. 20 days [13-50]). Functional status scores in the ICU (28±5. vs. 12±9) and ICU mobility scale (8 [8-10] vs. 5 [3-7]) were higher upon ICU discharge, while the duration of ventilator management (seven [4-9] vs. nine [8-18] days) and ICU length of stay (10 [10-14] vs. 17 [15-23] days) were shorter. They had fewer complications (two [18.2％] vs. 12 [80.0％]) and higher return-to-home rates (10 [90.9％] vs. two [13.3％]).Conclusion：Patients with severe COVID-19 who walked independently upon discharge had lower pre-admission frailty, fewer complications, shorter ventilator management duration, early mobilization, higher physical activity upon ICU discharge, shorter ICU stay, and higher return-to-home rates.

Objective: Previously, we reported that insulinoma-associated protein 1 (INSM1) immunohistochemistry (IHC) showed high sensitivity for neuroendocrine carcinoma of the uterine cervix and was an effective method for histopathological diagnosis, but that its specificity remained to be verified. Therefore, the aim was to verify the specificity of INSM1 IHC for a large number of non-neuroendocrine neoplasia (NEN) of the cervix. Methods: RNA sequences were performed for cell lines of small cell carcinoma (TCYIK), squamous cell carcinoma (SiHa), and adenocarcinoma (HeLa). A total of 104 cases of formalin-fixed and paraffin-embedded specimens, 16 cases of cervical NEN and 88 cases of cervical non-NEN, were evaluated immunohistochemically for conventional neuroendocrine markers and INSM1. All processes without antigen retrieval were performed by an automated IHC system. Results: The transcripts per million levels of INSM1 in RNA sequences were 1505 in TCYIK, 0 in SiHa, and HeLa. INSM1 immunoreactivity was shown only in the TCYIK. Immunohistochemical results showed that 15 cases of cervical NEN showed positive for INSM1; the positivity score of the tumor cell population and the stain strength for INSM1 were high. Two of the 88 cases of cervical non-NENs were positive for INSM1 in one case each of typical adenocarcinoma and squamous cell carcinoma. The sensitivity of INSM1 for cervical NEN was 94%; specificity, 98%; the positive predictive value, 88%; and the negative predictive value, 99%. Conclusion INSM1 is an adjunctive diagnostic method with excellent specificity and sensitivity for diagnosing cervical NEN. Higher specificity can be obtained if morphological evaluation is also performed.

An 85-year-old woman was transported to our hospital because of nausea and abdominal pain. Contrast-enhanced computed tomography revealed type IV hiatal hernia with incarcerated necrotic transverse colon. Emergency laparotomy was performed. When the incarcerated stomach and transverse colon were returned to the abdominal cavity, the transverse colon was resected and anastomosed due to necrosis. After the hiatal defect was closed, the Toupet method was also performed. No regurgitation or obstruction was observed after the operation, and the patient was discharged 63 days postoperatively. Here we report this rare case of intestinal necrosis due to type IV hiatal hernia and review the literature.

STUDY DESIGN: Retrospective case-control study, level 4. PURPOSE: To clarify the risk factors for late subaxial lesion after occipitocervical (O-C) reconstruction. We examined cases requiring fusion-segment-extended (FE) reconstruction in addition to/after O-C reconstruction. OVERVIEW OF LITERATURE: Patients with rheumatoid arthritis (RA) frequently require O-C reconstruction surgery for cranio-cervical lesions. Acceptable outcomes are achieved via indirect decompression using cervical pedicle screws and occipital plate–rod systems. However, late subaxial lesions may develop occasionally following O-C reconstruction. METHODS: O-C reconstruction using cervical pedicle screws and occipital plate–rod systems was performed between 1994 and 2007 in 113 patients with RA. Occipito-atlanto-axial (O-C2) reconstruction was performed for 89 patients, and occipito-subaxial cervical (O-under C2) reconstruction was performed for 24 patients. We reviewed the cases of patients requiring FE reconstruction (fusion extended group, FEG) and 26 consecutive patients who did not require FE reconstruction after a follow-up of >5 years (non-fusion extended group, NEG) as controls. RESULTS: FE reconstructions were performed for nine patients at an average of 45 months (range, 24–180 months) after O-C reconstruction. Of the 89 patients, three (3%) underwent FE reconstruction in cases of O-C2 reconstruction. Of the 24 patients, five (21%) underwent FE reconstruction in cases of O-under C2 reconstruction (p=0.003, Fisher exact test). Age, sex, RA type, and neurological impairment stage were not significantly different between FEG and NEG. O-under C2 reconstruction, larger correction angle (4° per number of unfixed segment), and O-C7 angle change after O-C reconstruction were the risk factors for late subaxial lesions on radiographic assessment. CONCLUSIONS: Overcorrection of angle at fusion segments requiring O-C7 angle change was a risk factor for late subaxial lesion in patients with RA with fragile bones and joints. Correction should be limited, considering the residual mobility of the cervical unfixed segments.

Transcatheter arterial embolization using N-butyl-2-cyanoacrylate (NBCA) for gastrointestinal arterial bleeding enables higher cessation rate and lower recurrent bleeding rate compared with conventional embolic materials including gelatin sponge, metallic coil, and polyvinyl alcohol (PVA) particle. Glue embolization is particularly effective in patients with coagulopathy. Even in the lower gastrointestinal tract, ischemic bowel complications by glue embolization are comparable to other agents. Glue embolization is also effective for arterial esophageal bleeding without any serious ischemic complications although the anatomy of the esophageal artery is complex and varied. For bleeding after abdominal surgery such as pancreaticoduodenectomy or hepatic lobectomy, interventional radiologists should be careful with indicating glue embolization because the presence of fewer collateral vessels can easily result in serious ischemic complications. Modified glue such as Glubran 2 (NBCA associated with methacryloxyfulfolane) can reduce the risk of ischemic complication due to its less thermal reaction, but the outcomes seem unsatisfactory.

The number of patients with diabetes mellitus (DM) in Japan is increasing. Progression of DM leads to the development of diabetic peripheral neuropathy, which causes foot sensory disturbances. This study examined the effect of DM on plantar tactile point pressure sensitivity (TPPS) and identified the site with the highest threshold of plantar TPPS. The subjects were 42 DM patients (aged 71.7±8.2 years) and 122 local elderly residents (aged 72.6±4.8 years). TPPS of eight sites, including the right and left halluces, hallux and fifth toe metatarsal heads, and heels was measured using the Semmes-Weinstein monofilament test. The measurement was performed three times at each site. The results were adopted when all repeated measurements were valid. The Friedman test was used for comparison among the four sites within the same group. The Mann-Whitney U test was used for comparison of sites between groups. A significance level of 5% was adopted. The ages of the DM patients were not significantly different, but the patients had significantly higher TPPS threshold for halluces, and hallux and fifth toe metatarsal heads, compared to the local elderly residents. The TPPS threshold was highest in the heels in both the DM patients and local elderly residents. The threshold of plantar TPPS increases in DM. It is important to evaluate both the forefoot and the heels.

BACKGROUND/AIMS: Left-sided diverticulitis is increasing in Japan, and many studies report that left-sided diverticulitis is more likely to be severe. Therefore, it is important to identify the features and risk factors for left-sided diverticulitis. We hypothesized that left-sided diverticulitis in Japan is related to obesity and conducted a study of the features and risk factors for this disorder in Japan. METHODS: Right-sided diverticulitis and left-sided diverticulitis patients (total of 215) were compared with respect to background, particularly obesity-related factors to identify risk factors for diverticulitis. RESULTS: There were 166 (77.2%) right-sided diverticulitis patients and 49 (22.8%) left-sided diverticulitis patients. The proportions of obese patients (body mass index > or =25 kg/m2, p=0.0349), viscerally obese patients (visceral fat area > or =100 cm2, p=0.0019), patients of mean age (p=0.0003), and elderly patients (age > or =65 years, p=0.0177) were significantly higher in the left-sided-diverticulitis group than in the right-sided-diverticulitis group. The proportion of viscerally obese patients was significantly higher in the left-sided-diverticulitis group than in the left-sided-diverticulosis group (p=0.0390). CONCLUSIONS: This study showed that obesity, particularly visceral obesity, was a risk factor for left-sided diverticulitis in Japan.

A 71-year-old man was given a diagnosis of saccular aneurysm of the aortic arch (maximum 48mm in diameter) at the age of 68. When he was 69 years old, he began to take steroids for autoimmune hepatitis (AIH). The following year, the aneurysm was enlarged to 52mm. Further examinations showed the aneurysm to extend to the ostium of the left subclavian artery. Since he had transient ischemic attacks, ultrasonography of the carotid arteries was performed. Bilateral internal carotid stenoses were detected, however, cold Xe CT showed an almost normal pattern of cerebral blood flow. We decided that operation was feasible using retrograde cerebral perfusion (RCP). Liver dysfunction due to AIH improved, and his steroid dosage was tapered. Using RCP, the no-touch technique and the elephant trunk procedure, he underwent the replacement of ascending aorta and aortic arch and was discharged without major complications. RCP and the no-touch technique might enable safer operations on patients with carotid stenoses.
