RESUMO
BACKGROUND: Irregular menstruation is a major health problem among women, although its association with nightshift work remains controversial. AIMS: To study the association between nightshift work and irregular menstrual cycle among female workers and investigate any differences according to sleep quality, working hours or obesity. METHODS: This study included female workers who underwent health examinations from 2012 to 2019. Nightshift work, working hours, sleep quality and menstrual cycles were assessed using self-administered questionnaires. Irregular menstrual cycle was defined as self-reported irregular or ≥36 days. Adjusted odds ratios and 95% confidence intervals (CIs) were calculated by multivariable logistic regression; adjusted hazard ratios (95% CIs) for incident irregular menstrual cycle were calculated by Cox proportional hazard models with time-dependent analysis. RESULTS: The study participants were 87 147 in the cross-sectional study and 41 516 in the longitudinal study. After adjusting for all covariates in the cross-sectional analyses, the odds ratio for prevalent irregular menstrual cycle among female nightshift workers versus the reference was 1.26 (95% CI 1.2-1.33). In the cohort study, the adjusted hazard ratio for incident irregular menstrual cycle among nightshift workers was 1.95 (95% CI 1.61-2.35) in the period after 6 years. No significant differences were observed among subgroups stratified by sleep quality, working hours or obesity. CONCLUSIONS: Nightshift work is associated with an increased risk of both prevalent and incident irregular menstrual cycle in female workers without significant interactions by sleep quality, working hours or obesity.

BACKGROUND AND PURPOSE: Data on the pregnancy outcome of neuromyelitis optica spectrum disorder (NMOSD) remain limited, especially for woman who had received immunosuppressive treatment before becoming pregnant. The aim was to evaluate the outcome of pregnancy amongst patients with NMOSD who attempted to become pregnant after NMOSD onset and to identify risk factors that predict pregnancy-related attack. METHODS: Medical records from 29 patients who attempted to become pregnant after NMOSD onset were retrospectively evaluated and the patients were interviewed for pregnancy outcomes. Pregnancy-related attack was defined as an attack that occurred during pregnancy or within 1 year of delivery. RESULTS: Amongst the 29 patients, 26 had 33 pregnancies after NMOSD symptom onset. The 33 pregnancies after NMOSD onset resulted in 24 live births (healthy neonates except one with low birth weight), six miscarriages and three elective abortions. Pregnancy-related attack occurred in nine (75%) of 12 pregnancies before initiation of immunosuppressive therapy, but in only five (24%) of 21 pregnancies after initiation of immunosuppressive therapy (P = 0.009). Multivariable analysis indicated that pregnancy-related attack was negatively associated with pregnancy after initiation of rituximab (odds ratio 0.048, 95% confidence interval 0.004-0.546). CONCLUSION: Successful pregnancy without maternal and neonatal complications may be feasible in patients with NMOSD. Rituximab treatment before pregnancy might help to prevent pregnancy-related attack in patients with NMOSD.

BACKGROUND AND AIMS: It is not known whether non alcoholic fatty liver disease (NAFLD) is a risk factor for diabetes in non obese, non centrally-obese subjects. Our aim was to investigate relationships between fatty liver, insulin resistance and a biomarker score for liver fibrosis with incident diabetes at follow up, in subjects who were neither obese nor centrally-obese. METHODS AND RESULTS: As many as 70,303 subjects with a body mass index (BMI) < 25 kg/m2 and without diabetes were followed up for a maximum of 7.9 years. At baseline, fatty liver was identified by liver ultrasound, insulin resistance (IR) by homeostatic model assessment of insulin resistance (HOMA-IR) ≥2.0, and central obesity by waist circumference (waist circumference ≥90 cm (men) and ≥85 cm (women). The Fibrosis-4 (FIB-4 score) was used to estimate extent of liver fibrosis. Cox proportional hazards models adjusted for confounders were used to estimate hazard ratios (aHRs) for incident diabetes. As many as 852 incident cases of diabetes occurred during follow up (median [IQR] 3.71 [2.03] years). Mean ± SD BMI was 22.8 ± 1.8 and 21.7 ± 2.0 kg/m2 in subjects with and without diabetes at follow up. In subjects without central obesity and with fatty liver, aHRs (95% CI) for incident diabetes at follow up were 2.17 (1.56, 3.03) for men, and 2.86 (1.50,5.46) for women. Similar aHRs for incident diabetes occurred with fatty liver, IR and the highest quartile of FIB-4 combined, in men; and there was a non significant trend toward increased risk in women. CONCLUSIONS: In normal weight, non-centrally obese subjects NAFLD is an independent risk factor for incident diabetes.

Double-lumen endobronchial tube placement is challenging. This study compared double-lumen tube placement with the Disposcope® , a wireless videostylet allowing real-time visualisation, with conventional blind placement. Patients undergoing elective thoracic surgery with normal airways requiring one-lung ventilation were randomly allocated into two groups (27 patients in each group). The Disposcope was used to assist left-sided double-lumen tube placement in one group, and conventional blind placement was performed in the control group. Placement in both groups was checked with fibreoptic bronchoscopy. The Disposcope-assisted group had a shorter total mean (SD) placement time (18.6 (2.5) s vs. 21.4 (2.9) s, p < 0.001), laryngoscopy to end of auscultation time (83.4 (3.0) s vs. 93.9 (5.7) s, p < 0.001) and total operation time (130.7 (6.1) s vs. 154.5 (6.3) s, p < 0.001). In the Disposcope-assisted group, the double-lumen tube was inserted in the correct side in all patients (100.0%), whereas in the conventional group, the double-lumen tube was placed in the correct side in 25 (92.6%) patients and in the wrong side in 2 (7.4%) patients; the difference was not significant (p = 0.150). In the Disposcope-assisted group, the double-lumen tube was inserted to the optimal depth in 24 (88.9%) patients, whereas in the conventional group it was inserted to the optimal depth in one (4.0%) patient. The Disposcope increased the success rate of double-lumen tube placement, and shortened the total operation time when compared with standard placement with confirmation using fibreoptic bronchoscopy, and may replace the conventional method.

An acute gastroenteritis (AGE) outbreak was reported in May 2013 in Gyeonggi Province, South Korea. Eight students who had eaten breakfast on 21 May 2013 at a high-school restaurant exhibited AGE symptoms. Our case-control study showed that a strong association was observed between AGE symptoms and fermented oyster consumption. Virological studies also indicated that noroviruses (NoVs) were detected from both clinical samples and fermented oyster samples, and multiple different genotypes (genogroups GII.4, GII.11 and GII.14) of NoVs were present in both samples. The nucleotide sequence similarity between the strains found in the clinical samples and those in the fermented oysters was more than 99·5%. Therefore, to prevent further outbreaks, proper management of raw oysters is necessary and the food industry should be aware of the risk of viral gastroenteritis posed by fermented oysters contaminated with NoVs.

BACKGROUND: It is unclear whether treating brain metastasis before starting systemic chemotherapy can improve survival compared with upfront chemotherapy in non-small-cell lung cancer (NSCLC) with asymptomatic cerebral oligo-metastases. PATIENTS AND METHODS: We undertook a randomized, controlled trial of 105 patients with one to four brain metastases, admitted to Samsung Medical Center between 2008 and 2013. Patients were randomly assigned to receive stereotactic radiosurgery (SRS) (49 patients) followed by chemotherapy or upfront chemotherapy (49 patients). The primary end point was overall survival (OS) and secondary end points included central nervous system (CNS) progression-free survival, progression to symptomatic brain metastasis and brain functional outcome. RESULTS: The median age was 58 years (range, 29-85) with ECOG 0-1 performance status, and 40% of patients were never smokers. Most patients had adenocarcinoma, and about half of patients had only one brain metastasis, while the rest had multiple cerebral metastases. The median OS time was 14.6 months [95% confidence interval (CI), 9.2-20.0] in the SRS group and 15.3 months (95% CI, 7.2-23.4) for the upfront chemotherapy group (P = 0.418). There was no significant difference in time to CNS disease progression [median, 9.4 months (SRS) versus 6.6 months (upfront chemotherapy), P = 0.248]. Symptomatic progression of brain metastases was observed more frequently in the upfront chemotherapy group (26.5%) than the SRS group (18.4%) but without statistical significance. CONCLUSIONS: Although this study included smaller sample size than initially anticipated due to early termination, SRS followed by chemotherapy did not improve OS in oligo-brain metastases NSCLC patients compared with upfront chemotherapy. Further study with large number of patients should be needed to confirm the use of upfront chemotherapy alone in this subgroup of patients. CLINICAL TRIALS NUMBER: NCT01301560.

OBJECTIVES: This study aimed to assess the relationship between socio-economic factors and community periodontal treatment needs in Korea. METHODS: Data were obtained from the year 2009 Korean National Health and Nutrition Examination Survey. Our analysis included 7510 survey participants over the age of 19 years. To assess the relationship between socio-economic factors and the need for periodontal scaling, we performed multivariate logistic regression analyses for data with a complex sampling structure. PASW statistics 19.0 (SPSS Inc., Chicago, IL, USA) was used to perform the statistical analyses, and the results were expressed as odds ratios (OR) with corresponding 95% confidence intervals (CIs). RESULTS: A very high percentage of Korean adults required periodontal scaling (71.5%). After adjusting for sex, age, and socio-economic factors, the need for periodontal scaling was associated with low levels of education (OR: 1.41, 95% CI: 1.03-1.93), low incomes (OR: 1.27, 95% CI: 1.01-1.60), employment as a service and sales worker (OR: 1.39, 95% CI: 1.10-1.77), and employment as a manual worker (OR: 1.31, 95% CI: 1.02-1.69). CONCLUSIONS: In South Korea, the need for periodontal scaling was associated with socio-economic factors, such as low levels of education, low incomes, employment as a service and sales worker and employment as a manual worker. Consequently, clinical and community dental hygienists should consider adults with these risk factors as belonging to high-priority subgroups to whom they should respond first.

Cytochrome P450 2C9 (CYP2C9) metabolizes many clinically important drugs including warfarin and diclofenac. We have recently reported a new allelic variant, CYP2C9*35, found in a warfarin hypersensitive patient with Arg125Leu and Arg144Cys mutations. Here, we have investigated the molecular basis for the functional consequences of these polymorphic changes. CYP2C9.1 and CYP2C9-Arg144Cys expressed in human embryonic kidney 293 cells effectively metabolized both S-warfarin and diclofenac in NADPH-dependent reactions, whereas CYP2C9-Arg125Leu or CYP2C9.35 were catalytically silent. However, when NADPH was replaced by a direct electron donor to CYPs, cumene hydroperoxide, hereby bypassing the CYP oxidoreductase (POR), all variant enzymes were active, indicating unproductive interactions between CYP2C9.35 and POR. In silico analysis revealed a decrease of the electrostatic potential of CYP2C9-Arg125Leu-POR interacting surface and the loss of stabilizing salt bridges between these proteins. In conclusion, our data strongly suggest that the Arg125Leu mutation in CYP2C9.35 prevents CYP2C9-POR interactions resulting in the absence of NADPH-dependent CYP2C9-catalyzed activity in vivo, thus influencing the warfarin sensitivity in the carriers of this allele.

AIM: To investigate the recovery of thiazolidinedione-induced body weight gain and haematopoietic changes after stopping pioglitazone treatment in patients with Type 2 diabetes. METHODS: This retrospective cohort study included 214 patients divided into three groups according to pioglitazone treatment status. The first study arm included patients who received pioglitazone for 38 months then interrupted this for 10 months (pioglitazone-interruption group). The second arm consisted of patients who received pioglitazone throughout the 48 months (pioglitazone-continuous group); the third arm included patients who had never received pioglitazone therapy (control group). RESULTS: Red blood cell count and haematocrit and haemoglobin levels decreased significantly, while body weight increased in the two pioglitazone-treated groups as compared with the control group at 38 months. Multivariate regression analysis showed that the reductions in red blood cell count/haemoglobin levels were associated with pioglitazone use. In the pioglitazone-interruption group, no recoveries of red blood cells, or haematocrit or haemoglobin levels were observed after stopping pioglitazone for 10 months compared with the pioglitazone-continuous group, but body weight gain decreased to a level that was significantly lower than that in the pioglitazone-continuous group and did not differ significantly from the control group. CONCLUSION: In this study, we observed a reversal of body weight gain but no recoveries in red blood cells or haematocrit or haemoglobin levels after stopping pioglitazone for 10 months in patients treated with pioglitazone for 38 months. This finding should prompt a reconsideration of the sustained effect of thiazolidinediones on the haematopoietic system in patients with Type 2 diabetes.

OBJECTIVES: To evaluate the reproducibility of measurement of the fetal left modified myocardial performance index (Mod-MPI) determined using a novel automated system. METHODS: This was a prospective study of 116 ultrasound examinations from 110 normal singleton pregnancies at 12 + 1 to 37 + 1 weeks' gestation. Two experienced operators each measured the left Mod-MPI twice manually and twice automatically using the Auto Mod-MPI system. Intra- and interoperator reproducibility were assessed using intraclass correlation coefficients (ICCs) and the manual and automated measurements obtained by the more experienced operator were compared using Bland-Altman plots and ICCs. RESULTS: Both operators successfully measured the left Mod-MPI in all cases using the Auto Mod-MPI system. For both operators, intraoperator reproducibility was higher when performing automated measurements (ICC = 0.967 and 0.962 for Operators 1 and 2, respectively) than when performing manual measurements (ICC = 0.857 and 0.856 for Operators 1 and 2, respectively). Interoperator agreement was also better for automated than for manual measurements (ICC = 0.930 vs 0.723, respectively). There was good agreement between the automated and manual values measured by the more experienced operator. CONCLUSIONS: The Auto Mod-MPI system is a reliable technique for measuring fetal left Mod-MPI and demonstrates excellent reproducibility.

Combined results based on morphological characters and analyses of partial sequences of the 16s rRNA and coI genes confirm the validity of a new, cryptic, symphurine tonguefish from the western North Pacific Ocean. Symphurus leucochilus n. sp., a diminutive species reaching sizes to c. 67 mm standard length, is described from nine specimens that were collected from fish-landing ports and from trawls made at c. 150 m off Taiwan and Japan. Symphurus leucochilus shares many similar features with those of Symphurus microrhynchus and that of several undescribed species that are morphologically similar to S. microrhynchus. Symphurus leucochilus has also been misidentified as Symphurus orientalis in fish collections because of shared similarities in some aspects of their morphology. The new species differs from all congeners by the following combination of meristic, morphological and pigmentation features: a predominant 1-2-2-2-2 pattern of interdigitation of proximal dorsal-fin pterygiophores and neural spines; 12 caudal-fin rays; 89-92 dorsal-fin rays; 76-80 anal-fin rays; 49-51 total vertebrae; four hypurals; 75-83 longitudinal scale rows; 32-35 transverse scales; 15-17 scale rows on the head posterior to the lower orbit; absence of a fleshy ridge on the ocular-side lower jaw and a membranous connection between the anterior nostril and lower part of the eye; a narrow interorbital space and dorsal-fin origin anterior to the vertical through the anterior margin of the upper eye; absence of both dermal spots at bases of anterior dorsal-fin rays and melanophores on the isthmus; uniformly yellow to light-brown ocular-side colouration without bands; dorsal and anal fins with alternating series of dark rectangular blotches and unpigmented areas; a uniform white blind side and a bluish-black peritoneum. Despite overall similarities in morphology between S. leucochilus and S. orientalis, as well as between two of the nominal species morphologically similar to S. microrhynchus, analyses of partial 16s rRNA and coI gene sequences show that S. leucochilus, S. orientalis and the two other nominal species represent three distinct lineages within the genus Symphurus.

1. Cyclooxygenase-2 (COX-2), along with TNF-α and other proinflammatory cytokines, was hyperinduced in H5N1- infected macrophages in vitro and in epithelial cells of autopsied lung tissues of infected patients. 2. The COX-2 mediated amplification of the proinflammatory response is rapid, and the effects elicited by the H5N1-triggered proinflammatory cascade are broader than those arising from direct viral infection. 3. Selective COX-2 inhibitors suppress the H5N1- hyperinduced cytokines in the proinflammatory cascade.

Rose geranium (Pelargonium graveolens, Geraniaceae) has anti-cancer and anti-inflammatory properties, and promotes wound healing. Similarly, Ganoderma tsugae (Ganodermataceae), Codonopsis pilosula (Campanulaceae) and Angelica sinensis (Apiaceae) are traditional Chinese herbs associated with immunomodulatory functions. In the present study, a randomised, double-blind, placebo-controlled study was conducted to examine whether the Chinese medicinal herb complex, RG-CMH, which represents a mixture of rose geranium and extracts of G. tsugae, C. pilosula and A. sinensis, can improve the immune cell count of cancer patients receiving chemotherapy and/or radiotherapy to prevent leucopenia and immune impairment that usually occurs during cancer therapy. A total of fifty-eight breast cancer patients who received chemotherapy or radiotherapy were enrolled. Immune cell levels in patient serum were determined before, and following, 6 weeks of cancer treatment for patients receiving either an RG-CMH or a placebo. Administration of RG-CMH was associated with a significant reduction in levels of leucocytes from 31·5 % for the placebo group to 13·4 % for the RG-CMH group. Similarly, levels of neutrophils significantly decreased from 35·6 % for the placebo group to 11·0 % for the RG-CMH group. RG-CMH intervention was also associated with a decrease in levels of T cells, helper T cells, cytotoxic T cells and natural killer cells compared with the placebo group. However, these differences between the two groups were not statistically significant. In conclusion, administration of RG-CMH to patients receiving chemotherapy/radiotherapy may have the capacity to delay, or ease, the reduction in levels of leucocytes and neutrophils that are experienced by patients during cancer treatment.

We describe two cases of postnatally diagnosed congenital diaphragmatic hernia (CDH) combined with pulmonary sequestration, both of which were diagnosed as isolated pulmonary sequestration on prenatal ultrasound. In these cases, prenatal ultrasonography demonstrated only a hyperechoic mass on the left lower lung and the diaphragm seemed intact. In each case both lungs showed otherwise normal development throughout pregnancy. Pulmonary sequestration may serve as a 'protector', preventing herniation of abdominal contents into the thoracic cavity. The co-occurrence of CDH may be obscured by a lung mass, especially on the left lower lung, and therefore it is necessary to deliver these infants at a tertiary center and parents should be counseled about the possibility of postnatal CDH.

BACKGROUND: Rituximab has been associated with hepatitis B virus reactivation (HBV-R). However, the characteristics and scope of this association remain largely undefined. METHODS: We completed a comprehensive literature search of all published rituximab-associated HBV-R cases and from the Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) MedWatch database. Literature and FDA cases were compared for completeness, and a meta-analysis was completed. RESULTS: One hundred and eighty-three unique cases of rituximab-associated HBV-R were identified from the literature (n = 27 case reports, n = 156 case series). The time from last rituximab to reactivation was 3 months (range 0-12), although 29% occurred >6 months after last rituximab. Within FDA data (n = 118 cases), there was a strong signal for rituximab-associated HBV-R [proportional reporting ratio = 28.5, 95% confidence interval (CI) 23.9-34.1; Empiric Bayes Geometric Mean = 26.4, 95% CI 21.4-31.1]. However, the completeness of data in FDA reports was significantly inferior compared with literature cases (P < 0.0001). Among HBV core antibody (HBcAb(+)) series, the pooled effect of rituximab-based therapy showed a significantly increased risk of HBV-R compared with nonrituximab-treated patients (odds ratio 5.73, 95% CI 2.01-16.33; Z = 3.33, P = 0.0009) without heterogeneity (χ(2) = 2.12, P = 0.5473). CONCLUSIONS: The FDA AERS provided strong HBV-R safety signals; however, literature-based cases provided a significantly more complete description. Furthermore, meta-analysis of HBcAb(+) series identified a more than fivefold increased rate of rituximab-associated HBV-R.

There have been few reports classifying the biophysical characteristics of Korean women with healthy skin. Consequently, the aim of this study was to find the most useful parameters for categorizing skin types based on a clinical assessment. One hundred and three female volunteers, aged 20-59, participated in this study. We conducted a self-evaluation questionnaire, a clinical assessment of the facial skin, and non-invasive measurements on the cheek under controlled environmental conditions. The questionnaire survey indicated that 72% of respondents had dry skin. However, results of the clinical assessment focusing on skin roughness and scaling of the cheek showed that 6 subjects had very dry skin (6%), 29 had dry skin (28%) and 68 had normal skin with sufficient moisture (66%). We analysed the correlation between the clinical assessment and biophysical parameters. As a result, we obtained six biophysical parameters that had relatively higher correlations with clinical assessment than other parameters. Our study provided general information about the physiological characteristics of normal skin in Korean women and suggested useful parameters for characterizing dry skin.

RESUMO
OBJECTIVE: The importance of continuous monitoring of fasting blood sugar (FBS) levels of diabetic patients has been established. MATERIALS AND METHODS: An observational prospective study was conducted. Our analysis included 1,700,796 individuals from the nationwide South Korean National Health Insurance System cohort. FBS variability was measured by standard deviation (SD). RESULTS: Kaplan-Meier curves demonstrated elevated disease probability in the higher FBS fluctuation group compared with the lower FBS fluctuation group. After adjusting for confounding variables, Cox proportional hazards analysis showed that the hazard ratios of 411 individuals in the highest quartile of SD variation of FBS were 1.77 (95% confidence interval 1.37-2.28, p<0.001) compared with the lowest quartile of SD variation of FBS. The impact of FBS fluctuation on the risk of cardiovascular diseases (CVDs), cerebrovascular diseases, CVD mortality and all-cause mortality in the highest quartiles of diabetic and non-diabetic individuals was statistically significant. CONCLUSIONS: Visit-to-visit FBS variability has prognostic value for predicting micro- and macrovascular disease, cardiovascular mortality, and all-cause mortality.
