[PURPOSE] To evaluate the efficacy and safety of acupuncture and moxibustion treatments in breech presentation, we report correction rates and adverse events for correcting breech presentation in our department.[PARTICIPANTS AND METHODS] Subjects were pregnant women who were diagnosed with breech presentation in our obstetrics and gynecology department and started acupuncture and moxibustion treatment between April 1, 2009 and October 31, 2018. The target patients were retrospectively investigated by medical records. The main items investigated were the status of the pregnant women at the time of acupuncture and moxibustion initiation (presence or absence of threatened preterm labor), treatment position (sitting or lateral position), correction rates and occurrence of adverse events. Successful correction was defined as the rate of head position after acupuncture and moxibustion treatments. Adverse events were defined as "unfavorable medical events occurring during or after treatment, regardless of causation."[RESULTS] There were 371 pregnant women in the study; among them 57 women were diagnosed with threatened preterm labor at the start of acupuncture and moxibustion treatment, including 21 pregnant women who were in the hospital. The sitting position was used for treatment for 45.2% (168 cases) of subjects and lateral position was used for 54.7% (203 cases). The correction rates were 72.2% (268/371). In pregnant women with threatened preterm labor who were hospitalized at the time of acupuncture and moxibustion initiation, the correction rates were 28.6% (6/21 cases), which was significantly lower than that of outpatient pregnant women. There was no significant difference in the rate of correction by treatment position between sitting and lateral position. There were no adverse events of vagal reflexes when the left lateral position was treated. The frequency of adverse events per number of procedures was 1.1% (21/1916) and per number of cases was 5.7% (21/371 cases). There were two cases of rupture of membranes with no apparent causal relationship.[CONCLUSION] The safest position for treatment in pregnant women was considered to be the left lateral position. Most of the adverse events were minor or moderate, but there were two cases of rupture of membranes with no apparent causal relationship. When performing acupuncture and moxibustion for breech presentation, it is necessary to work closely with the patient's obstetrician.

Objective : Carvedilol is a non-selective β blocker with an α blocking activity. Since this drug is highly fat-soluble, it can pass through the blood-brain barrier, and thus may induce depression and lower QOL. In the present study, physicians and pharmacists collaborated to evaluate the antihypertension effect of carvedilol and post-administration changes in QOL. Furthermore, the relationship between QOL and antihypertension effect was analyzed.
Design : Self-controlled study.
Patients and Methods : Subjects were outpatients with hypertension above the age of 70 years who visited one of 42 medical institutions in Japan between April 1995 and March 1996. A total of 243 patients were registered, and 10-20 mg of carvedilol was administered once a day for six months. Pharmacists assessed the QOL of these patients by asking 82 questions on three separate occasions : before administration and one and six months after administration. The antihypertensive effect of this drug was investigated in patients in whom all three QOL questionnaires were collected. The main test items were antihypertensive effect, changes in QOL (subjective QOL with a special emphasis on patient psychology), and the relationship between antihypertensive effect and QOL. The antihypertensive effect of this drug was statistically analyzed by a paired t-test, and changes in QOL were statistically analyzed using generalized estimating equations.
Results : All three QOL questionnaires were collected from a total of 146 patients. Their pre-administration systolic blood pressure was 159.6±1.4 mmHg, and diastolic blood pressure 94.0±0.9 mmHg, and their blood pressure decreased significantly one month after the start of administration. This antihypertensive effect of carvedilol persisted, and the systolic and diastolic blood pressure of these patients six months after the start of administration was 141.1±1.2 and 85.2±0.7 mmHg, respectively (significant decreases when compared to pre-administration levels ; both p<0.05).
Subjective QOL improved significantly after carvedilol administration. And, changes were not seen in sexual function. Changes in the five categories of subjective QOL were as follows : psychological stability, disease-induced inconvenience, and independence improved significantly after carvedilol administration, but changes were not seen in gratification or vitality. However, improvements in subjective QOL did not correlate with improvements in blood pressure.
Conclusions : The results of the present study showed that carvedilol improved QOL without negatively affecting sexual function. Subjective QOL reflects the psychological well-being of patients. In the present study, psychological stability, disease-induced inconvenience, and independence improved significantly, but changes were not seen in gratification or vitality. Since β blockers can suppress the central nervous system, they can reduce psychological stability, gratification and vitality. Even though carvedilol is highly fat-soluble, the results of non-clinical studies have shown that it does not suppress the central nervous system as much as propranolol. The results of the present study showed that carvedilol does not strongly suppress the central nervous system of humans. Moreover, significant changes in QOL were not seen between one and six months after the start of administration of carvedilol, suggesting that it is possible to estimate the QOL of patients on antihypertensive therapy after six months of administration by assessing their QOL one month after administration.

Objective:The topic model is a well-known method used in the field of natural language processing (NLP)that defines adocument as constructed of topics that combine specific t erms. This method is used to model topic co-occurrencemathematically. In this study,we extracted topics from featu re vectors of explicit documents called medical package insertsby using cluster analysis. Methods:We counted the terms(nouns)recognized by the morphological analysis engine MeCab and created a documentterm matrix. A value of“tf・idf”was calculated in this matrix for term weighting to avoid the effect of term frequency. We reduced the dimensionality of the matrix using singular v alue decomposition,which removed unnecessary data,and weextracted feature vectors attributed to each medical package insert. The distance between feature vectors was calculatedusing cosine distance,and cluster analysis was performed based on the distance between the vectors.Results:Cluster analysis on our document-term matrix show ed that medical package inserts of drugs that have the sameefficacy or active ingredient were included in the same cl uster. Moreover, using term weighting and dimensionalityreduction,we could extract topics from medical package inserts.Conclusion:We obtained a foothold to apply our findings t o the recommendation of similar drugs. Cluster analysis ofmedical package inserts using NLP can contribute to the pro per application of drugs. In addition,our study revealed thesimilarities of drugs and suggested possibilities for new applications from several points of view.
