ABSTRACT
Background@#There is a shortage of general practitioners in Japan. With the revision of educational guidelines, general practice (GP) education has improved. However, the amount of education on GP in medical schools remains inconsistent. This study examined the relationship between medical students’ amount of GP-related education and their subsequent choice of GP majors. @*Methods@#A retrospective cohort study was conducted in a teaching hospital in Japan. Participants were residents in the hospital. The exposure comprised compulsory lectures and training time for community-based medicine in medical schools. The outcome included participants choosing GP majors after their initial 2-year junior residency. @*Results@#Fifty-one participants were included in the final analysis. Of these, 14 majored in GP and 37 in non-GP after their initial 2-year junior residency. Of the participants who took GP lectures for 18 hours or more, 11 chose GP majors, and 18 chose non-GP majors (risk ratio, 2.78; 95% confidence interval [CI], 0.88–8.79). Of the participants who underwent training for 12 days or more, 10 chose GP majors, and 16 chose non-GP majors (risk ratio, 2.40; 95% CI, 0.87–6.68). @*Conclusion@#The results do not support the association between the amount of compulsory undergraduate education for community-based medicine and the subsequent increase in the number of residents choosing GP majors in Japan. Educators would do well to explore different approaches, such as improving the quality of education to increase the number of GP residents. Further research is needed to reach more definitive conclusions.
ABSTRACT
IntroductionAntigen testing is essential in the clinical management of COVID-19. However, most evaluations of antigen tests have been performed before the emergence of the Omicron variant. Thus, an assessment of the diagnostic performance of antigen tests for the detection of SARS-CoV-2 during the circulation of Omicron variant is required. MethodsThis prospective observational study evaluated QuickNavi-COVID19 Ag, a rapid antigen detection test between December 2021 and February 2022 in Japan, using real-time reverse transcription (RT)-PCR as a reference. Two nasopharyngeal samples were simultaneously collected for antigen testing and for RT-PCR. Variant analysis of the SARS-CoV-2 genomic sequencing was also performed. ResultsIn total, nasopharyngeal samples were collected from 1,073 participants (417 positive; 919 symptomatic; 154 asymptomatic) for analysis. Compared with those of RT-PCR, the sensitivity, specificity, positive predictive value, and negative predictive value were 94.2% (95% CI: 91.6%-96.3%), 99.5% (95% CI: 98.7%-99.9%), 99.2% (95% CI: 97.8%-99.8%), and 96.5% (95% CI: 94.8%-97.7%), respectively. The sensitivity among symptomatic individuals was 94.3% (95% CI: 91.5%-96.4%). Overall, 85.9% of sequences were classified as Omicron sublineage BA.1, 12.4% were Omicron sublineage BA.2, and 1.6% were Delta B.1.617.2. (Delta variant). Most of the samples (87.1%) had Ct values <25. ConclusionsThe QuickNavi-COVID19 Ag test showed high diagnostic performance for the detection of the SARS-CoV-2 Omicron sublineages BA.1 and BA.2 from nasopharyngeal samples.
ABSTRACT
IntroductionSince respiratory sample collection is an uncomfortable experience, simultaneous detection of pathogens with a single swab is preferable. We prospectively evaluated the clinical performance of a newly developed antigen test QuickNavi-Flu+COVID19 Ag (Denka Co., Ltd., Tokyo, Japan) which can detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses at the same time with a single testing device. MethodsIncluded were those who were suspected of contracting coronavirus disease 2019 (COVID-19) and referred to a PCR center at Ibaraki prefecture in Japan, between August 2, 2021 to September 13, 2021, when the L452R mutant strains of SARS-CoV-2 were prevalent. Additional nasopharyngeal samples and anterior nasal samples were obtained for the antigen test and were compared with a reference reverse transcription PCR (RT-PCR) using nasopharyngeal samples. ResultsIn total, 1510 nasopharyngeal samples and 862 anterior nasal samples were evaluated. For SARS-CoV-2 detection in nasopharyngeal samples, the sensitivity and specificity of the antigen test were 80.9% and 99.8%, respectively. The sensitivity and specificity using anterior nasal samples were 67.8% and 100%, respectively. In symptomatic cases, the sensitivities increased to 88.3% with nasopharyngeal samples and 73.7% with anterior nasal samples. There were three cases of discrepant results between the antigen test and the real-time RT-PCR. All of them were positive with the antigen test but negative with the real-time RT-PCR in SARS-CoV-2 detection. During the study period, influenza viruses were not detected. ConclusionA combo kit, QuickNavi-Flu+COVID19 Ag, showed an acceptable sensitivity and sufficient specificity for SARS-CoV-2 detection, especially using nasopharyngeal sample collected from symptomatic patients.
ABSTRACT
Antigen tests for severe acute respiratory coronavirus 2 sometimes show positive lines earlier than their specified read time, although the implication of getting the results at earlier time is not well understood. This study aimed to evaluate the clinical utility of an antigen test by evaluating the time period to get positive results and by comparing the test sensitivity with that of a digital immunoassay (DIA) test. We prospectively collected additional nasopharyngeal samples from patients who had already tested positive for SARS-CoV-2 by reverse transcription PCR. The additional swab was used for an antigen test, QuickNavi-COVID19 Ag, and the time periods to get positive results were measured. The sensitivity of QuickNavi-COVID19 Ag was also compared with that of a DIA. In 84 of 96 (87.5%) analyzed cases, the results of QuickNavi-COVID19 Ag were positive. The time to obtain positive results was 15.0 seconds in median (inter quartile range: 12.0-33.3, range 11-736), and was extended in samples with higher cycle thresholds (Ct) (p<0.001). Positive lines appeared within a minute in 85.7% of cases and within 5 minutes in 96.4%. The sensitivities of QuickNavi-COVID19 Ag and the DIA were 87.5% (95% confident interval [CI]: 79.2%-93.4%) and 88.6% (95%CI: 75.4%- 96.2%), respectively. Their results were concordant in 90.9% of cases, with discrepancies present only in cases with Ct values >32. QuickNavi-COVID19 Ag immediately showed positive results in most cases, and the time to a positive reaction may have indicated the viral load. In addition, the sensitivity of the test was comparable to the DIA.
ABSTRACT
IntroductionAntigen testing may help screen for and detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in asymptomatic individuals. However, limited data regarding the diagnostic performance of antigen tests for this group are available. MethodsWe used clinical samples to prospectively evaluate the analytical and clinical performance of the antigen test QuickNavi-COVID19 Ag. This study was conducted at a PCR center between October 7, 2020 and January 9, 2021. Two nasopharyngeal samples per patient were obtained with flocked swabs; one was used for the antigen test, and the other for real-time reverse transcription PCR (RT-PCR). The diagnostic performance of the antigen test was compared between asymptomatic and symptomatic patients, and the RT-PCR results were used as a reference. ResultsAmong the 1,934 collected samples, SARS-CoV-2 was detected by real-time RT-PCR in 188 (9.7%); 76 (40.4%) of these samples were from asymptomatic individuals. Over half of the total samples (1,073; 55.5%) were obtained from asymptomatic volunteers. The sensitivity of the antigen test was significantly lower for asymptomatic group than for symptomatic patients (67.1% vs 89.3%, p < 0.001). The specificity was 100% for both groups, and no false positives were observed among all 1,934 samples. The median Ct value for the asymptomatic group was significantly higher than that of the symptomatic group (24 vs 20, p < 0.001). ConclusionsThe QuickNavi-COVID19 Ag showed a lower sensitivity for asymptomatic group than for symptomatic patients. However, its specificity was consistently high, and no false positives were found in this study.
ABSTRACT
We conducted a prospective study in Japan to evaluate the diagnostic performance of the antigen test QuickNavi-COVID19 Ag using anterior nasal samples and to compare the degrees of coughs or sneezes induction and the severity of pain between anterior nasal collection and nasopharyngeal collection. A total of 862 participants were included in the analysis. In comparison to the findings of reverse transcription PCR using nasopharyngeal samples, the antigen test using anterior nasal samples showed 72.5% sensitivity (95% confidence interval [CI]: 58.3%-84.1%) and 100% specificity (95% CI: 99.3%-100%). Anterior nasal collection was associated with a significantly lower degree of coughs or sneezes induction and the severity of pain in comparison to nasopharyngeal collection (p < 0.001). The antigen test using anterior nasal samples showed moderate sensitivity but was less painful and induced fewer coughs or sneezes.
ABSTRACT
IntroductionSeveral antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed worldwide, but their clinical utility has not been well established. In this study, we evaluated the analytical and clinical performance of QuickNavi-COVID19 Ag, a newly developed antigen test in Japan. MethodsThis prospective observational study was conducted at a PCR center between October 7 and December 5, 2020. The included patients were referred from a local public health center and 89 primary care facilities. We simultaneously obtained two nasopharyngeal samples with flocked swabs; one was used for the antigen test and the other for real-time reverse transcription PCR (RT-PCR). Using the results of real-time RT-PCR as a reference, the performance of the antigen test was evaluated. ResultsA total of 1186 patients were included in this study, and the real-time RT-PCR detected SARS-CoV-2 in 105 (8.9%). Of these 105 patients, 33 (31.4%) were asymptomatic. The antigen test provided a 98.8% (95% confident interval [CI]: 98.0%-99.4%) concordance rate with real-time RT-PCR, along with a sensitivity of 86.7% (95% CI: 78.6%-92.5%) and a specificity of 100% (95% CI: 99.7%-100%). False-negatives were observed in 14 patients, 8 of whom were asymptomatic and had a low viral load (cycle threshold (Ct) >30). In symptomatic patients, the sensitivity was 91.7% (95% CI: 82.7%-96.9%). ConclusionQuickNavi-COVID19 Ag showed high specificity and sufficient sensitivity for the detection of SARS-CoV-2. This test is a promising potential diagnostic modality especially in symptomatic patients.
ABSTRACT
Some patients requiring medical care wish to continue living at home, so the establishment of a collaborative healthcare system reflecting each community’s characteristics is urgently needed. Medical social workers (MSWs) are one of the professions in this collaborative system. Even though practice guidelines for MSWs include community practice, the main duty of MSWs to date is to support patients at hospital discharge. We, therefore, conduct this literature review to identify desirable MSW’s practice in the community. Based on Japanese studies on MSW's community practice we initially searched, MSW-led interventions were extracted from case reports, and inhibitory factors and promoting factors were extracted from research papers and survey reports. The finding indicates that practice MSWs implemented were “establishment of a collaborative system involves multiple institutions and professionals”, “establishment of a community network that supports patients’ life in the community”, “activation of the community through establishment of opportunities (e.g. gathering places) for residents to interact”, and “promotion for activities in the entire community (e.g., organizing educational classes)”. Data searched were summarized in 4 inhibitory factors and 4 promoting factors, respectively. The inhibitory factors were “activity restrictions due to the rules of institutions MSWs belong to”, “predominance of discharge support in the assigned jobs”, “shortage of allocated workers”, and “ambiguity of job responsibilities unique to MSW”. The promoting factors were “recognition within and outside the hospital, regarding the effectiveness of MSW’s practice”, “promotion of collaboration involving multiple institutions, multiple professionals, and non-professionals in the community”, “meeting the needs of MSW-specific roles”, and “establishment of MSWs' position in the community and their duties inside the hospitals”. As a result, the following points were important to address, which helps establish MSW's community practice: practice that utilizes social workers' perspectives and approaches; building better working environment within the hospital; and establishment of MSW's roles in the community collaboration inside and outside the hospital.
ABSTRACT
<b>Purpose: </b>A report of effective occupational therapy for delirium patients with cancer is uncommon. We report a patient of carcinomatous meningitis, in whom her daily activity is improved by occupational therapy. <b>Case: </b>Firstly, we supported her meals and then started occupational therapy accepting her interest. Although degree of confusion and her performance status was not varied from beginning to end, she could concentrate our programmed works and change her way of feelings. Also occupational therapy promotes reminiscence about her life review and friendship among other patients even in delirium condition. <b>Conclusion: </b>Occupational therapy can reduce cancer patients' impatience, anxiety and solitary feelings and improve quality of life.
ABSTRACT
<b>Background</b>: In terminally ill patients with cancer, sleep disturbance makes worse their quality of life. Midazolam has not ever been used for the treatment of sleep disturbance in general wards of our hospital, used in palliative care unit of other hospital, however. <b>Method</b>: This is a retrospective study based on chart review. Twenty-eight patients who were treated with midazolam for sleep disturbance included in this study. We designed evaluation methods to strictly follow the actual chart descriptions. Efficacy was rated as good, fair, or poor. Safety was defined by the presence or absence of respiratory depression and hypotension. <b>Results</b>: The median administration periods and initial doses were 6 days (range, 1-151) and 5.0 mg/night (1.8-20.0), respectively. Fourteen patients showed good sleep a night after midazolam infusion, four and nine patients showed fair and poor sleep, respectively. No patient demonstrated a respiratory rate of less than 8/min and systolic blood pressure of <60 mmHg at any point during and after midazolam infusion. <b>Conclusion</b>: Intravenous midazolam appeared to be safe for sleep disturbance of terminally ill patients with cancer in general wards. A future improvement administration methods are necessary to treat for sleep disturbance more effectively as well as PCU.
ABSTRACT
<b>Purpose</b>: Acute hemorrhagic rectal ulcer (AHRU) commonly occurs in elderly who are bedridden for long time due to severe underlying diseases such as cerebral and myocardial infarction and their complications. However, it is uncommon in end-stage cancer patients receiving palliative care. We report a rare AHRU case in his forties who had lung cancer with paraplegia due to tumor invasion. <b>Case</b>: A male lung cancer patientwas admitted to our hospital for new-onset paraplegia caused by spinal cord invasion. On 25th day after admission, he suffered from a little rectal bleeding. From that day, a painless rectal bleeding becomes gradually increased. On 37th day, a massive bleeding was occurred. Endoscopy showed that there was no active bleeding but an exposed vessel and partial circumferential ulcer in the lower part of rectum, which was compatible with the finding of AHRU. The lesion was successfully treated by clipping and no re-bleeding was observed after clipping. He was discharge on 103rd day. <b>Conclusion</b>: AHRU should be considered in the differential diagnosis of a massive melena in end-stage cancer patients. Prompt diagnosis and therapy is important because this disease is curable even in the terminal stage to improve their quality of life. Palliat Care Res 2011; 6(1): 308-312
