Factors associated with anxiety and depression among caregivers of patients receiving medical home visits.

In recent years, Japan has promoted home visits to support older adults, with caregivers playing an important role. However, caregivers generally experience a high frequency of anxiety and depression, and the factors associated with these conditions among home visit caregivers remain unknown. To identify the associated factors, we conducted a questionnaire-based cross-sectional study of home visit caregivers in Tokushima Prefecture, Japan. The survey included caregivers' Hospital Anxiety and Depression Scale;sociodemographic items of patients and caregivers;and caregivers' perceptions of the home care environment, patients, and themselves. The questionnaires were sent to 379 caregivers;203 responded (53.6% response rate), of which 173 were valid (85.2% valid response rate). The prevalence of anxiety and depression was 43.9% and 69.4%, respectively. Multiple logistic regression analysis of factors associated with anxiety and depression showed that stable family finances (OR:0.69, 95% CI:0.48-1.00, p=0.049) and stable caregiver health (OR:0.45, 95% CI:0.30-0.68, p<0.001) were associated with anxiety. Further, stable family finances (OR:0.60, 95% CI:0.38-0.93, p=0.022), stable caregiver health (OR:0.49, 95% CI:0.30-0.81, p=0.005), and stable patient condition (OR:0.51, 95% CI:0.29-0.92, p=0.025) were associated with depression. These findings demonstrate that caregiver wellbeing is essential in home care settings. J. Med. Invest. 70 : 443-449, August, 2023.

Does student evaluation of on-demand video lectures vary with student characteristics? A questionnaire survey of medical students at Tokushima University.

The popularity of online classes in university education has grown rapidly since the COVID-19 outbreak. This study aims to examine the association between the detailed characteristics/various contexts of students and the evaluation of online classes. An online questionnaire survey administered to third- and fourth-grade medical students of Tokushima University in September 2021-with 101 (42.8%) valid responses-showed the respondents' general impressions, comprehension, convenience, and desire for online classes even after the pandemic ends were significantly higher for the on-demand lectures than for simultaneous online classes. Notably, students who did not do other things while watching video lectures (10.9%) rated on-demand lectures as facilitating significantly higher impression, comprehension, and convenience than those who did other things (89.1%). A multivariate analysis revealed that students who did not do anything else while watching, whose waking time changed slightly, who commuted to school for shorter periods, who were not good at morning lectures, and who watched at high speed rated the video lectures highly. Thus, video lectures are appreciated by students who are committed to learning, which is a positive result for the future of on-demand education. J. Med. Invest. 70 : 483-493, August, 2023.

Feelings toward medicine in remote areas among medical students aiming to become generalists : A comparison with other specialists.

Geographic maldistribution of physicians is a serious problem in Japan, resulting in a few physicians in remote areas. We distributed questionnaires to 396 medical students at Tokushima University from 2013 to 2016. We examined the intensity of medical students toward medicine in remote areas by using a visual analog scale and investigated what medical specialty they chose after two years of clinical training. The intensity of interest in medicine and the intensity of willingness to contribute to it in remote areas were statistically higher among medical students who intended to choose general medicine. After graduation, only five participants chose to specialize in general medicine. Of the 14 medical students who originally chose general medicine, six chose internal medicine, three chose general medicine, and the others chose surgery, neurosurgery, anesthesiology, orthopedics, or emergency medicine. This study demonstrated that medical students who intend to choose general medicine have a higher intensity of willingness to contribute to medicine in remote areas, indicating that the support program for these students to become general practitioners after graduation increases the number of physicians in remote areas.

Comparison of therapeutic responses between polymyalgia rheumatica and remitting seronegative symmetrical synovitis with pitting edema syndrome.

Polymyalgia rheumatica (PMR) and remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome are common inflammatory rheumatic diseases in the elderly. In this study, we investigated the difference of the therapeutic responses between patients with PMR and RS3PE syndrome. Twenty-four patients with PMR and 12 patients with RS3PE syndrome were treated with initial dosages of 10-20 mg per day oral prednisolone, and the dosages were then tapered. Percentages of patients with negative c-reactive protein (CRP) after 8-week treatment were significantly more in RS3PE syndrome than in PMR. Percentages of patients with relapse during one-year treatment were less likely to be in RS3PE syndrome than in PMR. These differences observed between the two disorders were not associated with the level of initial CRP. There was no significant difference in percentages of patients with prednisolone-free remission after two-year treatment between PMR and RS3PE syndrome. These results indicate that the early response to the treatment is greater in RS3PE syndrome than in PMR. J. Med. Invest. 70 : 145-149, February, 2023.

Complementary and alternative medicines chosen for specific health problems: Internet survey using the I-CAM-Q in Japan: A STROBE-compliant cross-sectional study.

This study investigated the different complementary and alternative medicines (CAMs) adopted by people in Japan, as well as the health problems treated with CAMs. Understanding more about this topic will facilitate the appropriate incorporation of CAMs into conventional medicine when treating health problems. Data were collected through an online survey based on the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q). The study examined CAM utilization among people aged 20 years or older; 164 valid responses were collected (18.9%). We adopted a cross-sectional design. We then compared the relationships between the specific health problems reported by participants, their self-help practices, and the kinds of healthcare specialists consulted. We also examined participants' reasons for using CAMs and their responses regarding the usefulness of the CAMs adopted. We found that self-help/CAM practices differed for specific health problems. Participants with musculoskeletal and heart problems were more likely to use poultices. Those with respiratory and digestive problems were more likely to practice yoga, tai chi, and qigong. Those with digestive and neurological problems were more likely to use aromatherapy. The I-CAM-Q questionnaire also revealed the purpose and usefulness of the CAMs utilized as well as the participants' attitudes regarding conventional medicine. The study showed that participants find physicians less helpful than other options for treating their health problems. Additionally, when asked whether it was helpful to consult with a specific professional for health problems, there was a higher percentage of participants who answered "Very helpful" for professionals, like massage, judo, acupuncture, and moxibustion therapists, than for physicians. The results of this study will help to inform medical providers of the most appropriate types of CAMs for dealing with various health problems.

Past infections are associated with low levels of anti-citrullinated protein autoantibodies in rheumatoid arthritis.

Background : Rheumatoid arthritis (RA), an autoimmune disease of unknown etiology, is believed to occur as the result of actions of genetic and environmental factors. In this study, we examined the relation of past histories about infectious diseases with the levels anti-citrullinated protein autoantibodies (ACPA) in RA. Methods : Results of a questionnaire about histories of infectious diseases were obtained from 85 patients with RA, and were analyzed. Results : Significantly lower level of ACPA was detected in patients with the history of tonsillitis, otitis media or urinary cystitis than in those without it. There was no difference in the level of ACPA in RA patients between with and without cold / influenza, rubella, chickenpox, herpes labialis or herpes zoster. When RA patients were divided into two groups, high-level and low-level ACPA, multiple logistic regression analysis revealed that the history of otitis media was a significantly independent factor for the low level of ACPA. There was no significant relation between the level of rheumatoid factor and histories of infectious diseases. Conclusion : This study clarified that the past history of otitis media is associated with the low level of ACPA in RA. J. Med. Invest. 67 : 182-188, February, 2020.

Japanese elderly individuals wish for enteral tube feeding more strongly for their parents than for themselves.

[Introduction] The purpose of this study was to investigate the differences in the preference of enteral tube feeding between elderly inhabitants of Mugi town, Tokushima Prefecture, Japan, and their parents in various physical conditions. [Methods] This population-based questionnaire survey studied 300 randomly selected participants aged 65-80 years. Respondents were to consider a situation where eating was difficult, and were questioned on their desire for tube feeding, using a visual analogue scale (VAS) ranging from "do not want tube feeding (0)" to "want tube feeding (100)." [Results] Valid responses of 103 (34.4%) participants were analyzed. Under conditions of being "healthy," "bedridden," "with dementia," and "bedridden and with dementia," the median (IQR) of the VAS values for the desire for tube feeding were 31.8 (3.3 to 83.8), 19.3 (2.4 to 52.3), 5.2 (0.7 to 18.9), 4.0 (0.3 to 15.2) for respondents and 55.2 (11.6 to 92.2), 48.7 (5.5 to 85.5), 9.0 (1.2 to 46.8), 5.1 (0.1 to 36.5) for parents, respectively. The VAS values for the parents were significantly higher (p=0.001, 0.002, 0.001, and 0.01, respectively for the four conditions described) for the same items. [Conclusion] Surrogate decisions made by family members often differ from what the patients would have desired. J. Med. Invest. 66 : 258-263, August, 2019.

Predictive factors associated with the therapeutic response in patients with polymyalgia rheumatica and remitting seronegative symmetrical synovitis with pitting edema syndrome.

Polymyalgia rheumatica (PMR) and remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome are common inflammatory rheumatic diseases in the elderly. In this study, we investigate predictive factors which correspond to subsequent disease control of PMR and RS3PE syndrome. Twenty four patients, which contained 18 PMR and 6 RS3PE syndrome, were treated with initial dosages of 10-20 mg per day oral prednisolone, and the dosage of prednisolone was then tapered. Significantly higher initial CRP was observed in patients with poor disease control than in those with good disease control afterwards. The number of patients with negative CRP after 4 weeks was significantly more in patients with good disease control after 1 year than in those with poor disease control. Patients were shown to be in good disease control status after 1 year when CRP after 4 weeks became negative even if they had initial high CRP. Our study clarify that to make CRP negative after 4 weeks is associated with subsequent suppression of the disease activity and with decreased dosages of corticosteroids. J. Med. Invest. 66 : 112-118, February, 2019.

Characteristics of medical students who would like to be a generalist physician and contribute to remote area medicine.

We administered a questionnaire to 5th grade medical students to examine the effect of community-based clinical practice on their attitudes to remote area medicine and their course after the graduation. Data from 192 students were obtained. The intensity of students' attitudes was estimated by using visual analogue scale. The intensities of the interest and a sense of fulfillment in remote area medicine were significantly increased after the practice. A significantly lower level of the intensity to become a generalist than that to become a specialist was seen in the students with low intensity in a sense of fulfillment. The percentages of the students who answered that they can work for 5 years or more in remote area were significantly lower in students with low intensity of a sense of fulfillment than in those with high intensity. A significantly higher percentage in students who worked at a familiar prefecture to them after the graduation was seen in female than in male. This study shows that the community-based practice is meaningful in increasing motivation which desire to work in remote area medicine, and that the motivation may affect their course after the graduation.

Comparison of the efficacy and safety of 10-mg empagliflozin every day versus every other day in Japanese patients with Type 2 Diabetes Mellitus: a pilot trial.

The terminal elimination half-life (t1/2) of empagliflozin is 13.1 hours. Accordingly, we hypothesized that the administration of empagliflozin every other day might improve glycemic control in patients with type 2 diabetes mellitus, not being inferior to the therapy every day. We investigated the clinical effects and safety of the addition of empagliflozin every day or every other day to type 2 diabetic patients with a poor control in glycemia. Thirteen Japanese patients diagnosed as type 2 diabetes mellitus recruited to this study. Subjects were divided into two groups; one was treatment with 10 mg of empagliflozin every day (Group A), the other was 10 mg of empagliflozin every other day (Group B). The comparable study of multiple clinical indexes between the 2 groups was made before and 8, 16, and 24 weeks after the treatment. After the treatment for 24 weeks, the HbA1c level was decreased both in group A (from 7.5%±1.1% to 6.5%±0.8%) and in group B (from 7.6%±0.8% to 7.2%±0.5%). This pilot trial suggested the possibility of 10-mg every other day administration with empagliflozin for Japanese patients with type 2 diabetes mellitus. J. Med. Invest. 64: 50-57, February, 2017.

Association between Mouth Breathing and Atopic Dermatitis in Japanese Children 2-6 years Old: A Population-Based Cross-Sectional Study.

As mouth breathing is associated with asthma and otitis media, it may be associated with other diseases. Therefore, this population-based cross-sectional study evaluated the association of mouth breathing with the prevalences of various diseases in children. Preschool children older than 2 years were included. A questionnaire was given to parents/guardians at 13 nurseries in Tokushima City. There were 468 valid responses (45.2%). We defined a subject as a mouth breather in daytime (MBD) if they had 2 or more positive items among the 3 following items: "breathes with mouth ordinarily," "mouth is open ordinarily," and "mouth is open when chewing." We defined subjects as mouth breathers during sleep (MBS) if they had 2 or more positive items among the following 3 items: "snoring," "mouth is open during sleeping," and "mouth is dry when your child gets up." The prevalences of MBD and MBS were 35.5% and 45.9%, respectively. There were significant associations between MBD and atopic dermatitis (odds ratio [OR]: 2.4, 95% confidence interval [CI]: 1.4-4.2), MBS and atopic dermatitis (OR: 2.4, 95% CI: 1.3-4.2), and MBD and asthma (OR: 2.2, 95% CI: 1.2-4.0). After adjusting for history of asthma and allergic rhinitis; family history of atopic dermatitis, asthma, and allergic rhinitis; and nasal congestion; both MBD (OR: 2.6, 95% CI: 1.3-5.4) and MBS (OR: 4.1, 95% CI: 1.8-9.2) were significantly associated with atopic dermatitis. In preschool children older than 2 years, both MBD and MBS may be associated with the onset or development of atopic dermatitis.

Community-based clinical education increases motivation of medical students to medicine of remote area: comparison between lecture and practice.

In this study, we administered a questionnaire to medical students to evaluate the effect of community-based clinical education on their attitudes to community medicine and medicine in remote area. Questionnaires were given 4 times to all the students from first-year to sixth-year. Of 95 students, 65 students (68.4%) who completed all questionnaires, were used in this study. The intensity of students' attitudes was estimated by using visual analogue scale. The intensity of interest, a sense of fulfillment and passion in medicine of remote area was significantly increased after the community-based practice. On the other hand, the level of understanding in medicine in remote area was increased by the lecture not by the practice. The intensity of desire both to become a generalist and a specialist was significantly increased when the grade went up. Most of sixth-year students desired to have abilities of a generalist and a specialist simultaneously. This study shows that the community-based practice is more meaningful in increasing motivation in medicine in remote area than the lecture, and suggests that it is important to prepare more courses to experience community medicine to increase the number of physicians who desire to work in remote area.

Treatment responses and their predictors in patients with rheumatoid arthritis treated with biological agents.

Biological agents represent an important advancement in for the treatment of rheumatoid arthritis (RA), but there is a subset of patients who do not improve despite therapy. This study aimed to determine the efficacy of biological agents for RA and to identify clinical factors that are associated with their response. We studied 98 patients with RA who started an initiating biological agent which was selected from infliximab, etanercept, adalimumab and tociliximab at 4 medical institutions. Etanercept was the most frequently used biological agent followed by infliximab although there was a difference in the selection of the biological agents among medical institutions. We found that etanercept achieved the highest treatment response, remission rate and drug survival rate. A high disease activity in the baseline disease activity score-c-reactive protein (CRP) was shown to be a negative predictor of the treatment response, and high patient global assessment was significantly less likely to achieve a good response. At week 4, decreases in 28 swollen joint counts and CRP were useful as predictors for sustaining the efficacy up to week 48. These data demonstrate that assessments of the disease activity at baseline and the early treatment response may be useful in predicting the efficacy and drug survival rate of biological agents.

Chest computed tomography of a patient revealing severe hypoxia due to amniotic fluid embolism: a case report.

INTRODUCTION: Amniotic fluid embolism is one of the most severe complications in the peripartum period. Because its onset is abrupt and fulminant, it is unlikely that there will be time to examine the condition using thoracic computed tomography (CT). We report a case of life-threatening amniotic fluid embolism, where chest CT in the acute phase was obtained. CASE PRESENTATION: A 22-year-old Asian Japanese primiparous woman was suspected of having an amniotic fluid embolism. After a Cesarean section for cephalopelvic disproportion, her respiratory condition deteriorated. Her chest CT images were examined. CT findings revealed diffuse homogeneous ground-glass shadow in her bilateral peripheral lung fields. She was therefore transferred to our hospital. On admission to our hospital's intensive care unit, she was found to have severe hypoxemia, with SpO2 of 50% with a reservoir mask of 15 L/min oxygen. She was intubated with the support of noninvasive positive pressure ventilation. She was successfully extubated on the sixth day, and discharged from the hospital on the twentieth day. CONCLUSION: This is the first case report describing amniotic fluid embolism in which CT revealed an acute respiratory distress syndrome-like shadow.

[A case of severe convulsion induced by hypophosphatemia and hypomagnesemia].

We experienced a case of severe convulsion induced by hypophosphatemia and hypomagnesemia. We should consider hypophosphatemia and hypomagnesemia as risk factors of convulsion in patients with long-term central intravenous nutrition.

An adult patient with Kabuki syndrome presenting with Henoch-Schönlein purpura complicated with pulmonary hemorrhage.

We present a case of a 33-year-old woman with Kabuki syndrome (KS) presenting with Henoch-Schönlein purpura (HSP). She was admitted to our hospital with a brain abscess in the lateral ventricle and meningitis. She had been diagnosed with KS. Skin eruptions had appeared on her lower extremities, with arthralgia, cough, and hemoptysis. She suddenly developed pulmonary hemorrhage and respiratory failure. We intubated her trachea and started mechanical ventilation in the intensive care unit (ICU). Skin biopsy revealed leukocytoclastic vasculitis with granular depositions of immunoglobulin A (IgA) in dermal vessel walls, and she was diagnosed as having HSP. Supportive management and prednisolone at 20 mg x day(-1) cured the pulmonary hemorrhage and respiratory failure. On ICU day 27, she was weaned from mechanical ventilation. Pulmonary hemorrhage as a complication of HSP is rare and sometimes fatal. KS is often associated with an increased incidence of infection and congenital heart disease. Susceptibility to infection and pulmonary hypertension due to congenital heart disease in this patient may have led to the development of the pulmonary hemorrhage. Supportive care and steroid therapy appeared to be beneficial in the treatment of this patient with HSP with pulmonary hemorrhage.
