Two cases of iatrogenic levofloxacin-resistant pre-XDR tuberculosis in Japan.

This case report discusses two instances of iatrogenically induced pre-extensively drug-resistant tuberculosis (pre-XDR TB). In both cases, the patients were initially diagnosed with tuberculosis and hospitalized in university hospitals. Nucleic acid amplification tests identified rifampicin-resistant tuberculosis, leading to a deviation from clinical guidelines.

Advancements in pelvic ring fracture surgery: Assessing INFIX screw placement accuracy with CT navigation.

The management of unstable pelvic ring fractures, typically resulting from high-energy trauma, presents a significant clinical challenge due to the complexity of injuries. While effective in many cases, the traditional stabilization methods are fraught with various complications that can significantly impact patient recovery and quality of life (QOL). This study aims to evaluate the efficacy and precision of the anterior subcutaneous internal fixator (INFIX) technique when used with intraoperative computed tomography (CT) navigation, a novel approach intended to mitigate the limitations of conventional treatment modalities.

Preoperative Body Composition Correlates with Postoperative Muscle Volume and Degeneration after Total Hip Arthroplasty.

Impaired muscle recovery after total hip arthroplasty (THA) may affect gait and activities of daily living. Bioelectrical impedance analysis (BIA) can assess body composition and muscle volume, and computed tomography (CT) can assess muscle volume and the fatty degeneration of muscle. This study aimed to explore the effectiveness of BIA, and the correlation between preoperative body composition and postoperative muscle volume and degeneration after THA using BIA and CT.

Predictors of hospital mortality and multidrug-resistant pathogens in hospitalized pneumonia patients residing in the community.

Background And Objective: The 2019 ATS/ADSA guidelines for adult community-acquired pneumonia (CAP) eliminated healthcare-associated pneumonia (HCAP) and considered it to be a form of CAP. This concept, however, was based on studies with relatively small sample sizes.

Methods: We investigated the risk factors of 30-day mortality, and methicillin-resistant Staphylococcus aureus (MRSA) and infections in patients with pneumonia coming from the community using the Diagnosis Procedure Combination database, a nationwide discharge database of acute care hospitals.

Hangeshashinto for prevention of oral mucositis in patients undergoing hematopoietic stem cell transplantation: a randomized phase II study.

Purpose: Oral mucositis (OM) is a side effect associated with cancer treatment. Hangeshashinto (HST), a Kampo medicine, was originally prescribed to treat diarrhea, gastritis, and stomatitis. Several reports have described the effects of HST for OM induced by chemotherapy in patients with gastric or colorectal cancer.

Thermal treatment of water-soluble particles formed by compounds composed of carbon nanobelts and C molecules.

It was previously shown that spherical particles are self-assembled by compounds composed of C-(6,6)CNB-C, where CNB stands for "carbon nanobelt", by mixing two individual solutions of C and (6,6)CNB molecules dissolved in 1,2-dichlorobenzene at room temperature. The particles are monodisperse in water thanks to their high absolute value of the zeta potential in water. In this report, we investigate the effect of thermal treatment of the particles on some changes in the physical properties and structures.

Do metal implants for total hip arthroplasty affect bioelectrical impedance analysis? A retrospective study.

Background: Evaluation of body composition after total hip arthroplasty (THA) is essential because it can be used to evaluate muscle and functional recovery. Muscle volume and degeneration are evaluated using computed tomography (CT). However, CT evaluation of muscle volume has several limitations, such as radiation exposure and high medical cost.

Minimally Invasive 360° Fusion Using a Combination of INFIX and Minimally Invasive Spinopelvic Fixation by Intraoperative Computed Tomography Navigation for Unstable Pelvic Ring Fracture: A Technical Note.

Objective: Fluoroscopy is often used in the surgery of unstable pelvic ring fractures, and improved safety in implant placement is an issue. An anterior subcutaneous pelvic fixator (INFIX) combined with a percutaneous screw has been reported to be a minimally invasive and effective surgical technique for unstable pelvic ring injuries. However, although percutaneous screw fixation is minimally invasive, its indications for fracture fixation and fractures with large fragment displacements in the vertical plane remain controversial.

Effect of spinal fusion on joint space narrowing of the hip: comparison among non-fusion, short fusion, and middle or long fusion.

Background: Lumbar fusion corrects spinal deformities and improves spinal complications. Hip osteoarthritis (OA) is strongly correlated with spinal mobility, and joint space narrowing of the hip after spinal fusion has gained attention. This study aimed to elucidate the effect of spinal fusion on hip joint space narrowing.

Associations between the perception of risk in radiation exposure and changes in smoking and drinking status after a disaster: The Fukushima Health Management Survey.

The risk for people evacuated from Fukushima following the Great East Japan Earthquake of developing cancer from radiation exposure may be lower than that associated with smoking and alcohol drinking. However, the perception of those risks may change risk-related behavior. Therefore, we investigated whether the perceived risk of radiation exposure was associated with the initiation and/or cessation of smoking and of drinking alcohol following the disaster.

The impact of spousal behavior changes on smoking, drinking and physical activity: The longitudinal survey of middle-aged and elderly persons in Japan.

The purpose of this study is to assess how one spouse's behavior change can influence their partner's successful behavior changes in smoking, drinking and physical activity. We used data from 10-wave prospective annual surveys of 9417 married couples (discrete-time person-years = 118,876) aged 50-59 years in the Longitudinal Survey of Middle-aged and Elderly Persons in Japan. A logistic generalized estimating equation model with discrete-time design was used among individuals who smoked at baseline to examine the impact of their spouse's health behaviors (i.

Effects of anti-mouse RANKL antibody on orthodontic tooth movement in mice.

Background/purpose: Orthodontic tooth movement is achieved by alveolar bone remodeling, and therefore the balance of bone resorption and formation is important. Receptor activator of nuclear factor-κB ligand (RANKL) plays a crucial role in bone resorption. We previously reported that tumor necrosis factor-α (TNF-α) is also important in bone resorption during tooth movement.

A preliminary study of suppression of candida infection by miconazole mucoadhesive tablets in oral or oropharyngeal cancer patients undergoing radiotherapy.

Elevated numbers of candida in the oral cavity often lead to oral candidiasis development in patients undergoing radiotherapy for oral or oropharyngeal cancer. This study aimed to verify the effect of miconazole mucoadhesive tablets on suppression of oral candida infection during radiotherapy. For this preliminary interventional study, miconazole mucoadhesive tablets were attached to the oral mucosa for 14 days from when grade 2 oral mucositis appeared in patients with oral or oropharyngeal cancer receiving radiotherapy, and the incidence of oral candidiasis was investigated.
