Laparoscopic sleeve gastrectomy as a bridge to colorectal cancer surgery for obese patients: a case report.

Background: Severe obesity greatly influences the difficulty of colorectal cancer surgery and has been reported to prolong operative time, increase the rate of laparotomy, and elevate increase postoperative complications. We investigated the efficacy of laparoscopic sleeve gastrectomy (LSG) for preoperative weight loss to ensure safe colorectal cancer surgery.

Case Presentation: A 51 year-old female with a body mass index of 43.

Clinical features and risk factors for delayed rupture of traumatic cerebral aneurysm: A case series.

Background: Traumatic cerebral aneurysms (TA) are a subset of traumatic cerebrovascular injury (TCVI). Misdiagnosis of TA can be fatal. To investigate factors that predict TA formation and the optimal timing for searching, we present four suspected cases of delayed TA rupture during hospitalization.

Development and validation of a novel overhead method for anteroposterior radiographs of fractured rat femurs.

We aimed to establish a new method of obtaining femur anteroposterior radiographs from live rats. We used five adult male Sprague-Dawley rats and created a femoral fracture model with an 8 mm segmental fragment. After the surgery, we obtained two femoral anteroposterior radiographs, a novel overhead method, and a traditional craniocaudal view.

Development and validation of prediction scores for the outcome associated with persistent inflammation, immunosuppression, and catabolism syndrome among patients with trauma.

Background: Persistent inflammation, immunosuppression, and catabolism syndrome (PICS) has impacted on long-term prognosis of patients with trauma. We aimed to identify patients with trauma at risk of PICS-related complications early in the intensive care unit (ICU) course.

Methods: A single-center retrospective cohort study was conducted.

Effectiveness of a Doctor Dispatch System Activated by an Advanced Automatic Collision Notification after a Single-Vehicle Accident: A Case Report.

A 79-year-old woman collided with a cliff in a passenger automobile. The fire department acknowledged an automated collision notification from the D-Call Net (DCN) at 1 min after the accident and called for doctors by helicopter ( "Doctor-Heli" [DH] in Japan) 9 min after the injury. The DH reached the victim 28 min after the injury, and examination revealed pain in the right side of her chest, tachypnea, and a weak radial artery pulse (indicating shock).

A case of sigmoid colon volvulus with transanal ileus tube placement and Sharon's operation performed safely.

Although endoscopic repair is often performed for sigmoid colon volvulus without intestinal necrosis, surgery is the common choice of treatment due to recurrence. With no established treatment, Hartmann's operation or sigmoid colon resection is often performed. We report a case of a 65-year-old man with transanal ileus tube placement before surgery for sigmoid colon volvulus to prevent recurrence and achieve intestinal decompression followed by Sharon's operation to achieve one-stage anastomosis.

A case of severe hemorrhagic shock caused by traumatic avulsion of uterine fibroid.

Case Presentation: A 40-year-old woman was injured in a motor vehicle accident. Physician-staffed helicopter emergency medical service (HEMS) was dispatched, and after the HEMS physician performed thoracostomy and tracheal intubation to relieve the tension pneumothorax and hemorrhagic shock, her carotid artery became unpalpable. The physician then decided to perform prehospital resuscitative thoracotomy.

Oncologic outcomes after laparoscopic versus open multivisceral resection for local advanced colorectal cancer: A meta-analysis.

Laparoscopic (lap) colectomies for advanced colorectal cancer (CRC) often require resection of other organs. We systematically reviewed currently available literature on lap multi-visceral resection for CRC, with regard to short- and long-term oncological outcomes, and compared them with open procedures. We performed a systematic literature search in MEDLINE, EMBASE, Google Scholar and PubMed from inception to November 30, 2020.

Initial entry via the left upper quadrant with an optical trocar in laparoscopic bariatric surgery.

Introduction: Laparoscopic bariatric surgery (BS) is not readily performed in Japan. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at a unique site in the left upper quadrant (LUQ). Herein, we describe the technique, its advantages, and outcomes.

Influence of new coronavirus pandemic on behavior and awareness of young nurses and nursing students in Japan.

Background: Although mental health disorders of health care workers in the coronavirus disease 2019 (COVID-19) pandemic have been focused, little is known about the psychological impact on nurses and the influence on their behavior and awareness, such as professionalism and views on life and death, in Japan where there are fewer cases of infection and deaths than in other countries. Moreover, the influence of the pandemic on nursing students is still unclear.

Methods: An online questionnaire survey was conducted among nurses and nursing students.

Successful one-stage laparoscopic procedure for de Garengeot hernia: a totally extraperitoneal repair-first approach.

The de Garengeot hernia is a femoral hernia in which the appendix migrates into the hernia sac. It is usually diagnosed intraoperatively due to its rarity and lack of clinical presentation typical to acute appendicitis. Although most cases need emergency operation due to incarceration, no standard procedure exists.

Suppression of liver transplant rejection by anti-donor MHC antibodies via depletion of donor immunogenic dendritic cells.

Background: We previously found two distinct passenger dendritic cell (DC) subsets in the rat liver that played a central role in the liver transplant rejection. In addition, a tolerance-inducing protocol, donor-specific transfusion (DST), triggered systemic polytopical production of depleting alloantibodies to donor class I MHC (MHCI) antigen (DST-antibodies).

Methods: We examined the role of DST-antibodies in the trafficking of graft DC subsets and the alloresponses in a rat model.

Laparoscopic transabdominal preperitoneal hernioplasty for recurrent obturator hernia: A case report.

Reports of recurrence after obturator hernia repair are few. We describe the case of an 89-year-old woman who presented to us with a thrice recurrent obturator hernia. She had undergone open non-mesh repair twice and then laparoscopic non-mesh repair.

Primary extraskeletal osteosarcoma of the mesentery: A case report.

Introduction: Extraskeletal osteosarcoma is a rare malignant soft tissue tumor without attachment to the bone. To the best of our knowledge, we present here the first report of a primary extraskeletal osteosarcoma of the mesentery in Japan.

Case Presentation: A 46-year-old female underwent a health examination, with no complaint.

Taxonomic re-examination of "Chloromonas nivalis (Volvocales, Chlorophyceae) zygotes" from Japan and description of C. muramotoi sp. nov.

Recent molecular data has strongly suggested that field-collected cysts of snow algae that are morphologically identifiable as the zygotes of Chloromonas nivalis are composed of multiple species. Motile vegetative cells, however, have not been directly obtained from these cysts because of the difficulties involved in inducing their germination. Recently, our comparative molecular analyses, using both field-collected and cultured materials, demonstrated that one Japanese lineage of "C.

Electronic and Thermoelectric Properties of Layered Oxychalcogenides (BiO)Cu Ch ( Ch = S, Se, Te).

We study the new details of electronic and thermoelectric properties of polycrystalline layered oxychalcogenide systems of (BiO)Cu Ch ( Ch = Se, Te) prepared by using a solid-state reaction. The systems were characterized by using photoemission (PE) spectroscopy and four-probe temperature-dependent electrical resistivity ρ( T). PE spectra are explained by calculating the electronic properties using the generalized-gradient approximation method.

Delayed Expression of Circulating TGF-β1 and BMP-2 Levels in Human Nonunion Long Bone Fracture Healing.

Background: The healing process of bone fracture requires a well-controlled multistage and sequential order beginning immediately after the injury. However, complications leading to nonunion exist, creating serious problems and costs for patients. Transforming growth factor-beta 1 (TGF-β1) and bone morphogenic protein 2 (BMP-2) are two major growth factors involved in human bone fracture healing by promoting various stages of bone ossification.

The Pedicled Omental Flap Technique for Treating Extensive Defects or Soft-Tissue Infection of the Pelvic Area: A Report of 2 Cases.

Severe trauma injuries, such as open pelvic fractures and degloving injuries, have recently become salvageable. However, extensive soft-tissue defects often remain and can lead to disuse atrophy of the extremities, prolonged hospital stays, and numerous other problems. Such injuries can be easily and effectively treated by a general trauma surgeon performing the pedicled omental flap technique.

Approaches to Quality Risk Management When Using Single-Use Systems in the Manufacture of Biologics.

Biologics manufacturing technology has made great progress in the last decade. One of the most promising new technologies is the single-use system, which has improved the efficiency of biologics manufacturing processes. To ensure safety of biologics when employing such single-use systems in the manufacturing process, various issues need to be considered including possible extractables/leachables and particles arising from the components used in single-use systems.

Acute and chronic acalculous cholecystitis associated with aortic dissection.

Acalculous cholecystitis is a rare but life-threatening disease, but its pathogenesis is not fully revealed yet. We experienced two acalculous cholecystitis cases associated with aortic dissection. In Case 1, acalculous cholecystitis occurred just after the exacerbation of the aortic dissection.

Pulmonary edema after laparoscopic hepatectomy in a patient with Budd-Chiari syndrome-associated hepatocellular carcinoma.

An 84-year-old man diagnosed with Budd-Chiari syndrome (BCS) developed a 20-mm hepatocellular carcinoma. We performed laparoscopic hepatectomy without complications, but the patient's percutaneous oxygen saturation gradually worsened and pulmonary edema was detected 50 minutes after extubation. He was subsequently re-intubated and received diuretic therapy.
