using small and large subunit ribosomal DNA (SSU, LSU rDNA) sequences, the Iranian population of E. pini fell in a clade including species of three genera Ektaphelenchus, Ektaphelenchoides, and Devibursaphelenchus in SSU, and a clade including species of Ektaphelenchus and Ektaphelenchoides in LSU tree, in close association with an isolate identified as E. pini in the latter phylogeny with high (0.99) Bayesian posterior probability (BPP). The comparisons with the type and French populations, as well as phylogenetic affinities of the species using ribosomal data, are discussed. This is the first report of E. pini from Iran, and its first simultaneous morphological and molecular phylogenetic study. New observations on some species of the genus were also presented and discussed.Background Patients with coronavirus disease 2019 (COVID-19) can unknowingly spread the virus to several people during the early subclinical period. Methods We evaluated the viral dynamics in various body fluid specimens, such as nasopharyngeal swab, oropharyngeal swab, saliva, sputum, and urine specimens, of two patients with COVID-19 from hospital day 1 to 9. Additional samples of the saliva were taken at 1 hour, 2 hours, and 4 hours after using a chlorhexidine mouthwash. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load was determined by real-time reverse transcriptase polymerase chain reaction (rRT-PCR). Results SARS-CoV-2 was detected from all the five specimens of both patients by rRT-PCR. The viral load was the highest in the nasopharynx (patient 1 = 8.41 log10 copies/mL; patient 2 = 7.49 log10 copies/mL), but it was also remarkably high in the saliva (patient 1 = 6.63 log10 copies/mL; patient 2 = 7.10 log10 copies/mL). SARS-CoV-2 was detected up to hospital day 6 (illness day 9 for patient 2) from the saliva of both patients. The viral load in the saliva decreased transiently for 2 hours after using the chlorhexidine mouthwash. Conclusion SARS-CoV-2 viral load was consistently high in the saliva; it was relatively higher than that in the oropharynx during the early stage of COVID-19. Chlorhexidine mouthwash was effective in reducing the SARS-CoV-2 viral load in the saliva for a short-term period.Background This study aimed to describe the current status of acute stroke care in Korea and explore disparities among hospitals and regions. Methods The 2013 and 2014 national stroke audit data and the national health insurance claims data were linked and used for this study. Stroke patients hospitalized via emergency rooms within 7 days of stroke onset were selected. Results A total of 19,608 patients treated in 216 hospitals were analyzed. Among them 76% had ischemic stroke; 15%, intracerebral hemorrhage (ICH); and 9%, subarachnoid hemorrhage (SAH). learn more Of the hospitals, 31% provided inpatient stroke unit care. Ambulances were used in 56% of cases, and the median interval from onset to arrival was 4.5 hours. One-quarter of patients were referred from other hospitals. Intravenous thrombolysis (IVT) and endovascular treatment (EVT) rates were 11% and 4%, respectively. Three-quarters of the analyzed hospitals provided IVT and/or EVT, whereas 47% of hospitals providing IVT and 67% of hospitals providing EVT had less than one case per month. Decompressive surgery was performed on 28% of ICH patients, and clipping and coiling were performed in 17.2% and 14.3% of SAH patients, respectively. There were noticeable regional disparities between the various interventions, ambulance use, arrival time, and stroke unit availability. Conclusion This study describes the current status of acute stroke care in Korea. Despite quite acceptable quality of stroke care, it suggests regional and hospital disparities. Expansion of stroke units, stroke center certification or accreditation, and connections between stroke centers and emergency medical services are highly recommended.Background Post-transplant cancer (PTC) is a critical complication after kidney transplantation. However, whether successfully cured PTC affects the long-term graft outcome remains unclear. Methods We retrospectively reviewed 1,629 kidney transplant recipients from 1995 to 2017 after excluding patients with post-transplant hematologic or advanced non-curable cancers and who underwent allograft nephrectomy because of cancer. Cured PTCs were defined as cancers treated with curative methods and/or adjuvant therapy without recurrence during ≥ 2 years. Propensity score matching was performed to match cured PTC patients with cancer-naïve patients (i.e., non-PTC group). Results During the median period of 7 years (maximum, 23 years), 70 patients (4.3%) had cured PTCs. The PTC group showed significantly higher risks of death-censored graft failure (adjusted hazard ratio [HR], 2.56 [1.05-6.23]), class II donor-specific antibodies (adjusted HRs, 3.37 [1.30-8.71]), estimated glomerular filtration rate 1 g (adjusted HR, 3.61 [1.92-6.79]) compared to non-PTC group. However, the risk of mortality was not different between the PTC and non-PTC groups. According to the cancer type, only urogenital cancer had a significant association with graft failure (adjusted HR, 4.26 [1.19-15.22]) and the gastrointestinal cancer showed elevated risk of T cell mediated rejection compared to non-PTC (adjusted HR, 20.44 [6.02-69.39]). Conclusion Appropriate monitoring of graft function is necessary in patients with cured PTCs.Background Since the recently announced Community Care Policy, there has been an opinion that Korea needs to establish an alternative medical model such as physician home visits. This study aimed to assess the need and willingness to pay (WTP) for physician home visits among the community-dwelling Korean older population and to determine the most important factors that influence older adults to decide to use a physician home visit service. Methods A total of 797 people aged 60 years or older who were randomly selected from a nationwide dataset using a multi-stage stratified sampling method answered a questionnaire on the need and WTP for physician home visits. Results A total of 39.3% of participants reported that they would like a physician home visit when they need help. Among older adults who needed physician home visits (n = 313), the WTP amount for physician home visits was 21,982 ± 17,546 KRW. Logit and Tobit regression analyses showed that the higher valuated need and WTP for physician home visits was associated with a lower level of physical/psychosocial functioning measured by EuroQol-five dimensions score (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.01-1.27; P = 0.035) and a higher level of satisfaction when using community-based services such as public health centers (OR, 1.32; 95% CI, 1.02-1.72; P = 0.034), social welfare centers and Gyeong-ro-dang (OR, 1.61; 95% CI, 1.04-2.50; P = 0.033; β = 8.39; standard error, 3.63; P = 0.021). Conclusion This study provides evidence that the decision to pay for a physician home visit service is based upon the complex interactions among an individual's physical and psychosocial functioning, personal experiences of service utilization, and demographic factors. The value for physician home visits should be qualified based on the empirical data of WTP, which comes from a consumer-centered perspective.Peer review is a crucial part of research and publishing. However, it remains imperfect and suffers from bias, lack of transparency, and professional jealousy. It is also overburdened by an increasing quantity of complex papers against the stagnant pool of reviewers, causing delays in peer review. Additionally, many medical, nursing, and healthcare educators, peer reviewers, and authors may not be completely familiar with the current changes in peer review. Moreover, reviewer education and training have unfortunately remained lacking. This is especially crucial since current initiatives to improve the review process are now influenced by factors other than academic needs. Thus, increasing attention has recently focused on ways of streamlining the peer review process and implementing alternative peer-review methods using new technologies and open access models. This article aims to give an overview of the innovative strategies for peer review and to consider perspectives that may be helpful in introducing changes to peer review. Critical assessments of peer review innovations and incentives based on past and present experiences are indispensable. A theoretical appraisal must be balanced by a realistic appraisal of the ethical roles of all stakeholders in enhancing the peer review process. As the peer review system is far from being perfect, identifying and developing core competencies among reviewers, continuing education of researchers, reviewer education and training, and professional engagement of the scientific community in various disciplines may help bridge gaps in an imperfect but indispensable peer review system.Influenza is an epidemical acute respiratory disease caused by viral infection. Several complications in the respiratory tract, such as pneumonia can occur. However, rare but serious neurological complications are also observed. Here, we described the prevalence, characteristics and suggestive pathomechanism of syncope after influenza infection season. Of 2.2% of patients diagnosed as influenza experienced syncope. None of the patients had severe cough, low blood pressure (BP) or dehydration. Patients suffered with frequent dizziness before syncope. Patient with long duration of loss of consciousness was more observed in those with high fever or positive orthostatic BP drop.Background We purposed to evaluate the seasonality and associated factors of the incidence of gout attacks in Korea. Methods We prospectively enrolled patients with gout attacks who were treated at nine rheumatology clinics between January 2015 and July 2018 and followed them for 1-year. Demographic data, clinical and laboratory features, and meteorological data including seasonality were collected. Results Two hundred-five patients (men, 94.1%) were enrolled. The proportion of patients with initial gout attacks was 46.8% (n = 96). The median age, body mass index, attack duration, and serum uric acid level at enrollment were 50.0 years, 25.4, 5.0 days, and 7.4 mg/dL, respectively. Gout attacks were most common during spring (43.4%, P less then 0.001) and in March (23.4%, P less then 0.001). A similar pattern of seasonality was observed in the group with initial gout attacks. Alcohol was the most common provoking factor (39.0%), particularly during summer (50.0%). The median diurnal temperature change on the day of the attack was highest in the spring (9.8°C), followed by winter (9.3°C), fall (8.6°C), and summer (7.1°C) (P = 0.027). The median change in humidity between the 2 consecutive days (the day before and the day of the attack) was significantly different among the seasons (3.0%, spring; 0.3%, summer; -0.9%, fall; -1.2%, winter; P = 0.015). One hundred twenty-five (61%) patients completed 1-year follow-up (51% in the initial attack group). During the follow-up period, 64 gout flares developed (21 in the initial attack group). No significant seasonal variation in the follow-up flares was found. Conclusion In this prospective study, the most common season and month of gout attacks in Korea are spring and March, respectively. Alcohol is the most common provoking factor, particularly during summer. Diurnal temperature changes on the day of the attack and humidity changes from the day before the attack to the day of the attack are associated with gout attack in our cohort.
