Immediate Effects of Stabilization Exercises on Trunk Muscle Activity during Jump Header Shooting: A Pilot Study.

This study aimed to clarify trunk muscle activity during jump header shooting and examine the immediate effects of trunk stabilization exercises on trunk muscle activity. Nineteen males who had played soccer for over 5 years were assigned to either the trunk stabilization exercise group or the control group. Muscle activity during jump header shooting was measured before and after intervention. The intervention in the trunk stabilization exercise group was trunk muscle training, whereas that in the control group was sitting. The phases of jump header shooting and the effects of the interventions were compared. In pre-intervention measurements, the internal oblique activity during the push-off phase and early floating phase was significantly greater than that during the late floating phase (p < 0.01667). In pre-intervention measurements, the muscle activity of the internal oblique increased from the push-off phase, prior to the increase in muscle activity of the rectus abdominis and external oblique, whereas the muscle activity of all abdominal muscles increased immediately after take-off. The trunk stabilization exercise intervention decreased the muscle activity of the erector spinae (p < 0.05). There seems to be a certain activation sequence in the abdominals during jump header shooting, and a single application of stabilization exercises could possibly reduce the activation of the back muscles.

Safety and effectiveness of the 300 IR sublingual house dust mite allergen immunotherapy tablet: 2-year interim analysis of a specified drug-use survey.

Background: The efficacy and safety of a house dust mite sublingual tablet (HDM-tab) have been demonstrated in clinical trials, but the findings must be confirmed in real-world use among more widespread patient populations. Materials & methods: A postmarketing drug-use survey is assessing the drug's safety and effectiveness during routine use for up to 4 years. This 2-year interim analysis reports data collected up to March 2020. Results: Of 545 registered outpatients, 526 were evaluable for safety and 371 for effectiveness. Most common adverse drug reactions were local reactions. Mean rhinitis severity score decreased from 2.5 ± 0.8 at baseline to 1.4 ± 0.9, 1.1 ± 0.8 and 1.0 ± 0.8 at 6 months, 1 year and 2 years, respectively. Conclusion: The HDM tab appears to be safe and effective in real-world conditions during 2 years of continuous use. Trial registration number: University hospital Medical Information Network (UMIN) Clinical Trials Registry identifier: UMIN000042840.

Preventive Effects of Grape Extract on Ischemia/Reperfusion-Induced Acute Kidney Injury in Mice.

Since grape extract (GE) contains oligomeric proanthocyanidins and numerous polyphenols, dietary GE supplements may exert protective effects against various diseases. The present study investigated the pharmacological effects of GE derived from Chardonnay in vitro and in vivo. GE (100 µg/mL) completely inhibited tumor necrosis factor-α-induced endothelin-1, monocyte chemoattractant protein-1, interleukin-1ß, and intercellular adhesion molecule-1 gene expression in cultured endothelial cells. GE also strongly stimulated the phosphatidylinositol 3-kinase (PI3K)/Akt/endothelial nitric oxide synthase (eNOS) pathway. In the in vivo study, the effects of GE on ischemic acute kidney injury (AKI) were examined using male C57bl/6J wild-type and eNOS-/- mice. Right nephrectomized mice were exposed to 45 min of ischemia in the left kidney and this was followed by reperfusion. Although renal functional parameters in AKI mice significantly increased 48 h after reperfusion, the administration of GE (0.1 and 1 mg/kg, intravenous (i.v.)) 5 min before ischemia dose-dependently improved post-ischemic renal dysfunction in wild-type mice. Renal histopathological studies on AKI mice revealed tubular necrosis, proteinaceous casts in tubuli, and medullary congestion. The administration of GE ameliorated this damage in wild-type mice, but not in eNOS-/- mice. Furthermore, GE significantly restored decreases in the renal nitric oxide metabolite content due to ischemia in wild-type mice, but not in eNOS-/- mice. Thus, eNOS is closely involved in the renoprotective effects of GE, strongly suggesting that GE supplements are useful as a prophylactic treatment for the development of ischemic AKI.

Autopsy of anaplastic carcinoma of the pancreas producing granulocyte colony-stimulating factor.

A 50-year-old man presented to a nearby hospital with high fever and anorexia. An abdominal tumor was detected, and he was referred to our hospital. A pancreatic tumor was detected by computed tomography and abdominal ultrasonography. He had high fever, leukocytosis, and high serum granulocyte colony-stimulating factor (G-CSF). We performed a tumor biopsy and histological examination revealed anaplastic carcinoma of the pancreas. Based on the diagnosis, we initiated chemotherapy using gemcitabine plus S-1. However, the tumor rapidly progressed and he deteriorated and died 123 days after admission. As immunohistochemical study showed positive staining for G-CSF in the tumor cell, we diagnosed the tumor producing G-CSF during autopsy. Anaplastic carcinoma of the pancreas producing G-CSF is very rare, with 10 cases, including ours, reported in the literature.
