Purpose: Thyroid transcription factor 1 (TTF-1) expression is a useful predictor of treatment efficacy in advanced non-squamous non–small cell lung cancer (NSCLC). This study aimed to evaluate whether TTF-1 could predict the effectiveness of chemotherapy versus chemoimmunotherapy in patients with non-squamous NSCLC with programmed death ligand-1 (PD-L1) expression between 1% and 49%. Materials and Methods: We conducted a retrospective study of patients with NSCLC who were treated with chemotherapy or chemoimmunotherapy between March 2016 and May 2023. The patients had histologically confirmed NSCLC, stage III-IV or postoperative recurrence, TTF-1 measurements, and PD-L1 expression levels between 1% and 49%. Clinical data were analyzed to evaluate the effect of TTF-1 expression on treatment efficacy. Results: This study included 283 of 624 patients. TTF-1–positive patients showed longer progression-free survival (PFS) and overall survival (OS) (PFS: 6.4 months [95% confidence interval (CI), 5.0 to 9.4] vs. 4.1 months [95% CI, 2.7 to 6.1], p=0.03; OS: 17.9 months [95% CI, 15.2 to 28.1] vs. 9.4 months [95% CI, 6.3 to 17.0], p < 0.01) in the chemotherapy cohorts (n=93). In the chemoimmunotherapy cohort (n=190), there was no significant difference in PFS and OS between TTF-1–positive and –negative groups (PFS: 7.6 months [95% CI, 6.4 to 11.0] vs. 6.0 months [95% CI, 3.6 to 12.6], p=0.59; OS: 25.0 months [95% CI, 18.0 to 49.2] vs. 21.3 months [95% CI, 9.8 to 28.8], p=0.09). Conclusion In patients with NSCLC with PD-L1 expression between 1% and 49%, TTF-1 expression was a predictor of chemotherapeutic, but not chemoimmunotherapeutic, efficacy.

We conducted a large-scale survey of sports injuries in college athletes. This study aimed to investigate trends in sports injuries and disabilities among college athletes by gender, discipline, individual and team competition, contact and noncontact competition, and other competition characteristics. A total of 1,137 college athletes (786 men and 351 women) were surveyed. A questionnaire survey was conducted to determine the club, regularity, and history of sports injuries and disorders (presence/absence, severity, time of injury, site of injury, diagnosis, and recurrence). The prevalence of sports injuries among college athletes was 59.7%. The prevalence was 74.7% in team and contact sports, with ankle and knee ligament injuries accounting for most injuries. The second highest prevalence rate was 66.7% for individual/contact sports, where martial arts-type sports are common. Elbow injuries were common due to the characteristics of martial arts-type sports. Chronic sports injuries of the ankle were common in noncontact/individual sports, and shoulder joint disorders were common in noncontact/team sports. Different trends in sports injuries and disabilities were found depending on the sport characteristics. Considering the characteristics of the sports is necessary to prevent sports injuries and disabilities.

Objectives: Diagnosis and treatment of osteoporosis are instrumental in obtaining good outcomes of hip surgery.Measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) is the gold standard for diagnosing osteoporosis. However, due to limited access to DXA, there is a need for a screening tool to identify patients at a higher risk of osteoporosis. We analyzed the potential utility of the Osteoporosis Self-assessment Tool for Asians (OSTA) as a screening tool for osteoporosis. Methods: A total of 1378 female patients who underwent hip surgery at 8 institutions were analyzed. For each patient, the BMD of the proximal femoral region was measured by DXA (DXA-BMD), and the correlation with OSTA score (as a continuous variable) was assessed. Receiver operating characteristic (ROC) curve analysis was performed to assess the ability of OSTA score to predict osteoporosis. Lastly, the OSTA score was truncated to yield an integer (OSTA index) to clarify the percentage of patients with osteoporosis for each index. Results: DXA-BMD showed a strong correlation with OSTA (r = 0.683; P < 0.001). On ROC curve analysis, the optimal OSTA score cut-off value of − 5.4 was associated with 73.8% sensitivity and 80.9% specificity for diagnosis of osteoporosis (area under the curve: 0.842). A decrease in the OSTA index by 1 unit was associated with a 7.3% increase in the probability of osteoporosis. Conclusions OSTA is a potentially useful tool for screening osteoporosis in patients undergoing hip surgery. Our findings may help identify high-risk patients who require further investigation using DXA.

The questionnaire was distributed to caregivers regarding their management for home medication therapy. The purpose of this questionnaire was to clarify the role of community pharmacists in city “Z”, Hiroshima in supporting this activity. The results were compared among seven administrative zones. The percentage of caregivers who had routinely administered medications to dependent patients was 81%. Of these, the percentage of caregivers who had encountered difficulty in medication administration to dependent patients was 66%. Only 13% of these caregivers had sought assistance from pharmacists in dealing with issues they faced in the administration of medications. The percentage of caregivers who had easy access to pharmacists was 44%. The percentage of caregivers who received pharmacist-initiated information about patients was 23%. Among the 7 administrative zones in city “Z”, the 2 zones (H-zones) with the highest percentage of elderly citizens, 38.7%, were compared with the other 2 zones (L-zones) with the lowest percentage of elderly citizens, 25.7%, regarding medication management by caregivers. It was observed that the frequency of missing side effects or crushing medicines by caregivers was higher in H-zones as compared to L-zones. The results of this research suggest that close cooperation between pharmacists and caregivers improves the quality of medication therapy management. In an aging society, pharmacist intervention could be very beneficial to providing support and information that would improve the quality of patients’ medication therapy.

A 53-year-old man was urgently hospitalized with chronic renal failure, congestive heart failure, pulmonary edema, and pneumonia. He received respiratory support and dialysis after hospitalization in the intensive care unit. Coronary arteriography revealed an old myocardial infarction and unstable angina (triple vessel disease). Surgery was planned. However, after dialysis under heparin administration, clot formation was noted in the dialyzer. Serological tests confirmed the presence of antibodies to heparin-platelet factor 4 complex ; accordingly, heparin-induced thrombocytopenia (HIT) was diagnosed. Coronary artery bypass surgery should preferably be performed early in the case of coronary artery disease. However, surgery during the acute phase of HIT when antibodies to heparin-platelet factor 4 complex (HIT antibodies) are present is associated with a very high risk of developing thromboembolism. There is no criterion regarding the optimal timing for surgery when HIT antibodies are present. Therefore, clinicians are often confused about this. In cases where the platelet count, D-dimer level, fibrinogen degradation product (FDP) level, and fibrinogen level improve, thrombin production due to HIT antibodies is thought to decrease. We considered that the improvement in these values suggests that the number of HIT antibodies decreases and thus HIT antibody activity would be reduced. We evaluated the platelet count, D-dimer level, FDP level, and fibrinogen level over time and accordingly determined the optimal timing for surgery. In the present case, argatroban administration was started after HIT developed, and the platelet counts increased gradually ; the D-dimer and FDP levels decreased, whereas there were no significant changes in the fibrinogen levels. Although HIT antibodies were still present, we performed off-pump coronary artery bypass grafting under the administration of argatroban when the platelet count, D-dimer, and FDP values improved. The patency of coronary bypass grafts was confirmed postoperatively ; the patient did not develop thromboembolism during the perioperative period and was discharged without complications. When HIT antibodies are present, an improvement in platelet count, D-dimer, and FDP values is thought to be useful in determining the optimal timing of surgery.

An 83-year-old woman who had an attack of fever, fatigue, and lumbar pain was hospitalized as an emergency. Detailed investigations revealed that she had urinary infection, infectious spondylitis, and bacteremia with Streptococcus pneumonia, for which she received antimicrobial therapy. After 12 days in hospital, enhanced computed tomography showed that the aortic arch had expanded, with fluid collection. Though there had been no imaging findings by computed tomography scan on admission. We thought this was an infected thoracic aortic aneurysm with Streptococcus pneumonia, and continued to administer the antibiotic drugs for infection control. After 14 days in hospital, she developed hoarseness and complained of severe back pain. Emergency computed tomography scan showed that the aortic arch had further expanded to 66 mm in size and that much more fluid had collected. We decided it was an impending rupture of the rapidly-expanding infected thoracic aortic aneurysm, and we then performed an emergency operation. The infected portion of the thoracic aorta was resected. The ascending, arch, and descending portions of the aorta were replaced with rifampicin-bonded synthetic graft, and then omental wrapping was performed. Antimicrobial administration was continued after surgery. The postoperative course was uneventful. The infection was successfully controlled. She was discharged without complications. No signs of recurrent infection have been observed for 1 year and 6 months after operation.
