Selection of and Retention in Surgical Specialty during Early Career in Japan.
The number of surgeons is decreasing in Japan. We investigated the trend and factors influencing surgeons' selection of and retention in surgical specialty. In 2016, we obtained data of biennial surveys conducted by the government, and analyzed the annual data of doctors up to the latest available survey at that time (survey, 1994-2014; medical license acquisition, 1993-2014). ⋯ The retention rate in females declined continuously to 48.4% in 2002, stabilized thereafter, and then increased from 47.6% in 2006 to 50.8% in 2014. The retention rate after 10 years (1993-2003) was almost stable (72.4%) in males, but increased to 57.5% in females, and the gender difference tended to decrease. Younger doctors tend to value their private life, and may not choose or continue to practice surgery unless working conditions in surgery improve and income is commensurate with their work.

Differential Diagnosis of COVID-19: Importance of Measuring Blood Lymphocytes, Serum Electrolytes, and Olfactory and Taste Functions.
Coronavirus disease 2019 (COVID-19) is associated with various symptoms and changes in hematological and biochemical variables. However, clinical features, which can differentiate COVID-19 from non-COVID-19, are not clear. We therefore examined the key clinical features of COVID-19 and non-COVID-19 patients. ⋯ Fatigue, loose stool, diarrhea, nasal obstruction, olfactory dysfunction, and taste dysfunction were the key symptoms of COVID-19. Furthermore, hyperlipidemia and ARB may be risk factors of COVID-19. In conclusion, leucocytes, leucocyte fractions, CRP, LDH, and electrolytes are useful indicators for COVID-19 diagnosis.

Multidisciplinary Approach to Prevent de novo Hepatitis B in Patients with Rheumatoid Arthritis.
The reactivation of hepatitis B virus (HBV) in patients with rheumatoid arthritis (RA) is currently a social problem. Our hospital has established a project team, which consisted of medical staff including doctors, nurses, pharmacists, and technicians, to prevent HBV reactivation and subsequent de novo hepatitis B in 2015. To verify the usefulness of the team, we aimed to examine the implementation rate of HBV screening tests in patients with RA in 2011, 2015, and 2018. ⋯ Of the 767 patients who completed HBV screening in 2018, 157 patients (20.5%) had previously resolved HBV infection (HBsAg-negative but HBsAb- and/or HBcAb-positive). During a mean follow-up of 41.0 months, reactivation of HBV was observed in 10 out of the 157 patients (6.4%); however, none developed de novo hepatitis B. In conclusion, our multidisciplinary approach to prevent de novo hepatitis B is considered useful.

Potential Predictors of Poor Prognosis among Critical COVID-19 Pneumonia Patients Requiring Tracheal Intubation.
Coronavirus disease 2019 (COVID-19) is a global public health concern that can be classified as mild, moderate, severe, or critical, based on disease severity. Since the identification of critical patients is crucial for developing effective management strategies, we evaluated clinical characteristics, laboratory data, treatment provided, and oxygenation to identify potential predictors of mortality among critical COVID-19 pneumonia patients. We retrospectively utilized data from seven critical patients who were admitted to our hospital during April 2020 and required mechanical ventilation. ⋯ Compared with survivors, non-survivors tended to be never smokers (0 pack-years vs. 30 pack-years, p = 0.08), to have higher body mass index (31.3 kg/m2 vs. 25.3 kg/m2, p = 0.06), to require earlier tracheal intubation after symptom onset (2.7 days vs. 5.5 days, p = 0.07), and had fewer lymphocytes on admission (339 /μL vs. 518 /μL, p = 0.05). During the first week after tracheal intubation, non-survivors displayed lower values for minimum ratio of the partial pressure of oxygen to fractional inspiratory oxygen concentration (P/F ratio) (44 mmHg vs. 122 mmHg, p < 0.01) and poor response to intensive therapy compared with survivors. In summary, we show that obesity and lymphopenia could predict the severity of COVID-19 pneumonia and that the trend of lower P/F ratio during the first week of mechanical ventilation could provide useful prognostic information.

Visualizing the Process of Disaster Mental Health Services in the Joso Flood by Network Analyses of Emails.
Joso City, Ibaraki Prefecture, Japan was severely affected by flooding of the River Kinugawa in September 2015. Local psychiatric organizations immediately began providing disaster mental health services (DMHS). In post-disaster settings, DMHS involving organizational interventions by multiple regional institutions are required to support disaster victims. ⋯ In the acute phase, which lasted about 1 month, support and swift decision-making were essential for directing large numbers of staff. In the mid- to long-term phase, support for staff to share information and experience in small groups was observed. Network analyses have revealed that disaster medical teams must change their communication styles during the mission to adapt to different health needs corresponding to each post-disaster phase.
