In the 1980s, some researchers started using the word "multimorbidity", which is defined as "the co-existence of two or more long-term conditions in an individual". Multimorbidity has become one of the most important topics in recent primary care because of its clinical significance. Multimorbidity is more common among the elderly, and was suggested to be associated with female sex, lower socio-economic status and mental disease. Multimorbidity is associated with a higher mortality, lower quality of life and reduced functional status. It is also associated with the treatment burden such as consultation frequency, fragmented healthcare provision and inadequate polypharmacy. Multimorbidity has negative impact on health care resource use such as hospital visits, unexpected admission and total health care costs. However, the total picture and health care effects of multimorbidity have only been reported in observational studies, and there is little evidence of which interventions are effective for multimorbidity patients. In this review paper, we carried out a literature review of high-quality reports from Japan and overseas. We provide an overview of the current situation of multimorbidity research and highlight the research gaps. Based on these results, we would like to propose approaches for multimorbidity patients in clinical settings.

In recent years, the integration of mental health into primary care has become a global trend, as it is recognized to be effective for providing appropriate treatment, improving outcomes, and using resources appropriately. Therefore, in many countries, mental health education in primary care has been developed and delivered. However, systematic training on mental health for family physicians has not been sufficiently provided in Japan. We performed a scoping review in order to clarify the mental health competencies of primary care physicians by analyzing the educational curricula in other countries using thematic analysis. The competencies extracted were comprehensive and classified into three domains: "general competencies in primary care," "general competencies in mental health in primary care," and "specific competencies in mental health in primary care". In the future, it will be necessary to create a competency list based on the reported data and formulate a model curriculum based on the current situation in Japan.

We have conducted driving fitness evaluations for post-illness patients in our clinic since 2008. Many patients expressed a desire to resume driving; thus, primary care physicians and rehabilitation staff collaborated to establish an evaluation system. We conducted cognitive dysfunction evaluation, driving simulator evaluation, and evaluation at driving schools. Among 160 patients, we evaluated 87 to be fit to drive, and eight to be unfit. We describe the significance and challenges of assessing patients' driving aptitude in primary care.

Purpose: We report a case whose anal pain accompanied by rectal cancer was remarkably eliminated by subarachnoid phenol block and sacral nerve root thermocoagulation. Case Report: The subject was a sixty-one-year old male. His anal pain failed to respond to opioid whereas his pain was alleviated by subarachnoid phenol block, but was exacerbated a few weeks later. This relapsing pain was completely eradicated by sacral nerve root thermocoagulation. Conclusion: Anal pain associated with rectal cancer recurrence of pelvic space is sometimes hard to be controlled only by subarachnoid phenol block, but there is a possibility of pain control by combination use with sacral nerve root thermocoagulation.

This study compared the hemodynamic performance of the Carpentier-Edwards PERIMOUNT Magna bioprosthesis (Magna) with the Carpentier-Edwards PERIMOUNT bioprosthesis (CEP) for aortic valve stenosis (AS). Between January 2005 and May 2010, 164 patients underwent aortic valve replacement for AS with either the Magna (n=68) or the CEP (n=96) at our institute. Patients undergoing a concomitant mitral valve procedure were excluded from this study. The 21-mm Magna and CEP prostheses were the most frequently used during this period. Transthoracic echocardiography was postoperatively performed within 2 weeks. The peak velocity (PV) of the Magna was significantly lower than that of the CEP (2.59±0.36 vs. 2.75±0.47 m/s ; p=0.022). The mean pressure gradient (PG) was not significantly different. For the 19-mm prostheses, the mean PG and PV of the Magna were significantly lower than those of the CEP [16.4±4.5 vs. 19.7±6.4 mmHg ; p=0.034 (PG) and 2.70±0.36 vs. 3.03±0.49 m/s ; p=0.008 (PV)]. The effective orifice area (EOA) of the Magna was larger than that of the CEP [19 mm : 1.29±0.18 vs. 1.11±0.24 cm² (p=0.007) ; 21 mm : 1.46±0.23 vs. 1.42±0.18 cm² (p=0.370) ; and 23 mm : 1.70±0.34 vs. 1.52±0.25 cm² (p=0.134)]. In this study, the EOA of the Magna was approximately 80% of that described in the manufacture's description. Patient-prosthesis mismatch (PPM ; EOA index≤0.85 cm²/m²) was seen in 26.8% of patients with the Magna and in 47.2% of patients with the CEP (p=0.018). Severe PPM (EOA index≤0.65 cm²/m²) was not seen in any patients with the Magna. The EOA of the 19-mm Magna was significantly larger and the mean PG was lower than those of the 19-mm CEP. Compared with the CEP, the Magna significantly reduced the incidence of PPM, and had superior hemodynamic performance.

Prepulse inhibition (PPI) is considered to be one of the most promising neurophysiological indexes for translational research in psychiatry. Impairment of PPI has been reported in several psychiatric diseases, particularly schizophrenia, where PPI is considered a candidate intermediate phenotype (endophenotype) of the disease. Recent findings from a variety of research areas have provided important evidence regarding PPI impairment. Human brain imaging studies have demonstrated the involvement of the striatum, hippocampus, thalamus and frontal and parietal cortical regions in PPI. In addition, several genetic polymorphisms, including variations in the genes coding for Catechol O-methyltransferase, Neuregulin 1, nuclear factor kappa-B subunit 3 and serotonin-2A receptor were related to PPI; and these findings support PPI as a polygenetic trait that involves several neurotransmitter pathways. Early psychosis studies suggest that PPI disruption is present before the onset of psychosis. Also, discrepancy of PPI impairment between children and adults can be found in other psychiatric diseases, such as autistic spectrum disorders and posttraumatic stress disorder, and comprehensive investigation of startle response might contribute to understand the impairment of the neural circuitry in psychiatric diseases. Finally, recent studies with both Asian and Caucasian subjects indicate that patients with schizophrenia exhibit impaired PPI, and impaired sensorimotor gating might be a global common psychophysiological feature of schizophrenia. In conclusion, studies of PPI have successfully contributed to a better understanding of the fundamental neural mechanisms underlying sensorimotor gating and will certainly be most valuable in devising future approaches that aim to investigate the complex pathogenesis of psychiatric diseases.

Objective: Hospitals throughout Japan are being integrated and reorganized under the government's regional medical care plan. However, the effects on cardiovascular surgery practice remain unknown. In the year 2016, our institution employed hospital integration; we report its effects on patients with type A acute aortic dissection who underwent emergency surgery. Methods: This study included 89 patients who underwent emergency surgery for type A acute aortic dissection from May 2012 to December 2020. Evaluation items included preoperative patient factors, number of surgeries, surgical mortality, referral rate, patient transport time, transport distance, number of surgeries performed by young cardiovascular surgeons, and overtime work for surgery. Patients were categorized into pre-(group P: 29 patients) and post-integration (group A: 60 patients) groups, which were retrospectively compared. Results: Preoperative factors were not significantly different between the two groups. Operations accounted for 29 and 60 in groups P and A, respectively; they increased significantly after integration (p=0.005). Surgical mortality was 27.6 and 15% in groups P and A, respectively, with no significant difference (p=0.2). The referral rate was 17 (58.6%) and 21 (35%) patients in groups P and A, respectively; group A displayed a significantly lower referral rate (p=0.04). The interval from the onset of symptoms to arrival at the surgery cite was significantly reduced (p=0.01) in group A (112±140 min) compared to group P (206±201 min). There was no significant difference in the transfer distance between groups P (13.9±14.8 km) and A (13.5±16.2 km). The number of surgeries performed by young surgeons increased in 9 cases (31%) in group P and 34 cases (56.7%) in group A (p=0.02). Overtime work was substantially reduced:446±154 min in group P and 349±112 min in group A. Conclusion: Hospital integration resulted in increased number of acute aortic dissection surgeries and decreased interval time from the onset of symptoms to arrival at the surgery cite. The young surgeons performed more surgeries and reduced their overtime work.
