Objective While much attention is given to the fifth vital sign, the utility of the 4 classic vital signs (blood pressure, respiratory rate, body temperature, and heart rate) has been neglected. The aim of this study was to assess a possible association between vital signs and the Sequential Organ Failure Assessment (SOFA) score in patients with sepsis. Methods We performed a prospective, observational study of 206 patients with sepsis. Blood pressure, respiratory rate, body temperature, and heart rate were measured on arrival at the hospital. The SOFA score was also determined on the day of admission. Results Bivariate correlation analysis showed that all of the vital signs were correlated with the SOFA score. Multiple regression analysis indicated that decreased values of systolic blood pressure (multivariate regression coefficient [Coef] = -0.030, 95% confidence interval [CI] = -0.046 to -0.013) and diastolic blood pressure (Coef = -0.045, 95% CI = -0.070 to -0.019), increased respiratory rate (Coef = 0.176, 95% CI = 0.112 to 0.240), and increased shock index (Coef = 4.232, 95% CI = 2.401 to 6.062) significantly influenced the SOFA score. Conclusion Increased respiratory rate and shock index were significantly correlated with disease severity in patients with sepsis. Evaluation of these signs may therefore improve early identification of severely ill patients at triage, allowing more aggressive and timely interventions to improve the prognosis of these patients.

ObjectivesThe present study investigated the incidence of hyperammonemia in urinary tract infections and explored the utility of urinary obstruction relief and antimicrobial administration to improve hyperammonemia.MethodsThis was an observational study. Subjects were patients who were diagnosed with urinary tract infection and hospitalized between June 2008 and June 2009. We measured plasma ammonia levels on admission in patients who were clinically diagnosed with urinary tract infection and hospitalized. We assessed each patient's level of consciousness on admission using the Glasgow Coma Scale (GCS) and performed urine and blood cultures. We also assessed hearing prior to hospitalization using the Eastern Cooperative Oncology Group performance status (ECOG-PS). In cases with high ammonia levels on admission, plasma ammonia and GCS were measured 24 hours and 5–7 days later.ResultsSixty-seven candidates were enrolled; of these, 60 cases (89.6%) with bacterial cell counts ≥104 CFU/mL were studied. Five cases (8.3%) presented with high plasma ammonia levels. Cases with hyperammonemia were significantly more likely to present with low GCS scores and urinary retention rate. All five cases received antimicrobial therapy with an indwelling bladder catheter to relieve urinary retention. The case 5 patient died shortly after admission due to complicated aspiration pneumonia; in the remaining cases, plasma ammonia levels were rapidly normalized and the level of consciousness improved.ConclusionsThe occurrence of hyperammonemia in urinary tract infections is not rare. The cause of hyperammonemia is urinary retention obstruction. Therefore, along with antimicrobial administration, relief of obstruction is important for the treatment of hyperammonemia caused by this mechanism.

ObjectivesThis study investigated what kinds of experiences influence regional quota (chiikiwaku) medical students’ motivation to practice community healthcare (CH), and the mechanism of this influence, by focusing on their experiences in a community-based medical education (CBME) programme.DesignA qualitative thematic analysis based on interviews.SettingParticipants were recruited from the chiikiwaku students of Kobe University, Japan, using purposive sampling.ParticipantsFourteen students participated. The median (IQR) age of participants was 23 (23–24); half were sixth-year and half fifth-year students.AnalysisFrom September to December 2018, the interviews were audiorecorded and transcribed verbatim. Data were analysed according to the ‘Steps for Coding and Theorisation’ method. Our theoretical framework comprised three internal motives (ie, needs, cognitions and emotions) and their subordinate motivation theories self-determination theory, expectancy-value theories, and positive and negative emotions, respectively.ResultsThree mechanisms and corresponding experiences emerged. The first mechanism, envisioning and preparing for practising CH, included corresponding experiences—empathy for the community, grasping the demands for CH, understanding the practices of CH, finding a role model and diminishing the conflicts between personal life and career. The second mechanism, belonging to a supportive community, included the robust construction of students’ CH community and harmonisation with community residents. The third mechanism, psychological effects included the affect heuristic and framing effect. Student experiences brought about the changes and influences described in the presented mechanisms, and had both positive and negative impacts on their motivation towards CH. These results can be interpreted through the multifaceted lenses of motivation theories.ConclusionsThe authors revealed that motivation mechanisms of medical students towards CH derived from positive interaction with community residents, healthcare professionals and other students, and from exposure to attractive community environments and cultures. These experiences should be incorporated into CBME programmes to further encourage positive attitudes towards CH.

BackgroundThe aim of this study was to evaluate the clinical usefulness of a semiquantitative procalcitonin kit for assessing severity of sepsis and early determination of mortality in affected patients.MethodsThis was a prospective, observational study including 206 septic patients enrolled between June 2008 and August 2009. Disseminated intravascular coagulation (DIC), Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation (APACHE) II scores were measured, along with semiquantitative procalcitonin concentrations. Patients were divided into three groups based on their semiquantitative procalcitonin concentrations (group A, <2 ng/mL; group B ≥ 2 ng/mL < 10 ng/mL; group C ≥ 10 ng/mL).ResultsA significant difference in DIC, SOFA, and APACHE II scores was found between group A and group C and between group B and group C (P < 0.01). Patients with severe sepsis and septic shock had significantly higher procalcitonin concentrations than did patients with less severe disease. The rate of patients with septic shock with high procalcitonin concentrations showed an upward trend. There was a significant (P < 0.01) difference between the three groups with regard to numbers of patients and rates of severe sepsis, septic shock, DIC, and mortality.ConclusionSemiquantitative procalcitonin concentration testing can be helpful for early assessment of disease severity in patients with sepsis. Furthermore, it may also help in predicting early mortality in septic patients. Based on the level of semiquantitative procalcitonin measured in patients with suspected sepsis, a timely decision can be reliably made to transfer them to a tertiary hospital with an intensive care unit for optimal care.

Eosinophilic gastrointestinal diseases are delayed-type chronic allergic disorders that show gastrointestinal eosinophil dense infiltration, with an exaggerated Th2-type immune reaction considered to be an important mechanism. These diseases can be roughly divided into two types: eosinophilic esophagitis, mainly found in young and middle-aged men, and eosinophilic gastroenteritis, which is found in both genders equally. A diagnosis of eosinophilic esophagitis is suspected when characteristic endoscopic findings, including longitudinal furrows and rings, are noted. However, characteristic endoscopic abnormalities are rarely found in cases with eosinophilic gastroenteritis, so multiple biopsy sampling from the apparently normal gastrointestinal mucosal surface is important for making an accurate diagnosis. The administration of systemic glucocorticoid is the standard treatment for eosinophilic gastroenteritis, while acid inhibitors and topical glucocorticoid swallowing therapy are effective for eosinophilic esophagitis. Anti-cytokine therapies for eosinophilic gastrointestinal diseases are currently under development.
