RESUMO

The present study compared trends in antimicrobial resistance patterns in pathogens isolated from skin and soft-tissue infections (SSTIs) in Japan with those of a nationwide survey conducted in 2013. Three organisms that caused most of the SSTIs were collected from 12 dermatology departments in medical centers and 12 dermatology clinics across Japan between April 2019 and August 2020. A total of 390 strains, including 267 Staphylococcus aureus, 109 coagulase-negative staphylococci (CNS), and 14 Streptococcus pyogenes strains were submitted to a central laboratory for antimicrobial susceptibility testing. Patient demographic and clinical information was collated. Methicillin-resistant S. aureus (MRSA) was detected in 25.8% (69/267) of the S. aureus strains. The prevalence of MRSA between the present study and the 2013 survey did not differ significantly. Furthermore, there were no significant differences in MIC values and susceptibility patterns of the MRSA strains to other agents, regardless of a history of hospitalization within 1 year or invasive medical procedures. Methicillin-resistant CNS (MRCNS) was detected in 48.6% (53/109) of CNS isolates, higher than the 35.4% prevalence in the 2013 survey. This difference could be attributed to the heterogeneity in the members of the MRCNS, which comprises multiple staphylococci species, between the 2013 and 2019 surveys. However, it was noted that the susceptibility profiles of the MRCNS to each antibiotic were not significantly different from those identified in the 2013 survey. Most strains of S. pyogenes were susceptible to each antibiotic, similar to the 2013 survey. Continuous monitoring of trends in pathogen and susceptibility profiles is important to advise local public health efforts regarding the appropriate treatment of SSTIs.

RESUMO

The importance of informing women with epilepsy (WWE) of pregnancy-related issues when they are of reproductive age is well recognized. However, in Japan, education on pregnancy-related issues for these patients is insufficient. Obstetricians encounter patients who have self-discontinued their medications upon realizing they are pregnant. In this study, we aimed to assess the needs and understand knowledge levels regarding pregnancy-related issues among Japanese WWE. We contacted 400 board-certified epileptologists and asked them to administer our questionnaire to their patients; 51 responses were analyzed. Among all participating WWE, 100% were taking medication at the time of the study, 34% had given birth, and 63% expressed a desire to have children in the near future. Additionally, the median questionnaire score on pregnancy-related matters was as low as 9.5 out of 13 points. Only 31% of WWE knew that the mode of delivery is not always cesarean delivery. Among WWE, 62.7% stated that they had received counseling about pregnancy-related matters. Opinions differed regarding the optimum timing for counseling according to whether patients had received counseling. As for topics WWE wished to have explained to them, inheritance of epilepsy by their children ranked highly. The average satisfaction level with counseling was 5.6 of 7 points. Regarding satisfaction with counseling, there was a significant difference between WWE who expressed a desire to receive information from obstetricians and those who did not. In summary, we believe that our study shows that Japanese WWE remain ill-informed about pregnancy-related issues and that existing counseling must be revised. Obstetricians must play a role in preconception counseling.

RESUMO

Self-perception of people with Down Syndrome (DS) was originally studied in the United States in 2011; this study indicated that 99% of people with DS are happy with their lives. In this study, we investigated self-perceptions of people with DS in Japan and compared the results to the previous study made in the United States. The participants (n = 300) were 12 years old or older and members of Japan Down Syndrome Society (JDS). The questionnaire was collected between 30 October 2015 and 26 November 2015. Of 96(32%) responses, 76 (97%) agreed they are happy with their lives. We found that most people with DS in Japan also feel positive about themselves and their lives. Along with the start of Non-Invasive Prenatal Testing in Japan, DS draws an attention from Japanese people because maternal age has been increasing. This has resulted in the growth of the number of prenatal tests marketed in Japan. Therefore, we expect our results to be relevant to genetic counseling for the couples considering prenatal tests or parents raising their children with DS so that they have a clearer image about life with DS and can better visualize their life plans.

RESUMO

Despite studies of the mechanism underlying the intracellular localization of membrane proteins, the specific mechanisms by which each membrane protein localizes to the endoplasmic reticulum, Golgi apparatus, and plasma membrane in the secretory pathway are unclear. In this study, a discriminant analysis of endoplasmic reticulum, Golgi apparatus and plasma membrane-localized type II membrane proteins was performed using a position-specific scoring matrix derived from the amino acid propensity of the sequences around signal-anchors. The possibility that the sequence around the signal-anchor is a factor for identifying each localization group was evaluated. The discrimination accuracy between the Golgi apparatus and plasma membrane-localized type II membrane proteins was as high as 90%, indicating that, in addition to other factors, the sequence around signal-anchor is an essential component of the selection mechanism for the Golgi and plasma membrane localization. These results may improve the use of membrane proteins for drug delivery and therapeutic applications.

RESUMO

The prevalence of Panton-Valentine leukocidin gene (pvl)-positive community-acquired methicillin-resistant Staphylococcus aureus USA300 clone, which is designated as the ST8-staphylococcal cassette chromosome (SCC) mec type IV (ST8-IV) lineage, is a major public health concern worldwide. Thus, to elucidate the prevalence and characteristics of pvl-positive community-onset MRSA in Japan, we conducted a molecular epidemiological analysis for 854 S. aureus isolates obtained from outpatients with skin infections during 2013 and 2014. The isolation rate of MRSA was 25.6% (219 isolates), and the ratio of pvl-positive MRSA was 13.2% (29 isolates). Notably, the proportion (93.8%) of pvl-positive isolates was particularly high among MRSA isolates from Ishigaki island in Okinawa. Pulsed-field gel electrophoresis and multilocus sequence typing showed that the pulsotype C isolates (11 isolates) were typical USA300 clones with arginine catabolic mobile element (ACME) type I-CC8-IV lineages and prevalent on the main island of Japan (Honshu). Pulsotypes A (11 isolates) and B (four isolates) consisted of ACME-negative CC8-IV clones and were specific for Ishigaki island. Both USA300 and Okinawa-Ishigaki specific clones were associated with deep-seated skin infections, such as furuncle and cellulitis. Pulsotypes D (two isolates) and E (one isolate) were ACME-negative clonal complex (CC) 59-IV clones and were related to superficial skin infections, such as impetigo. Our findings revealed that pvl-positive MRSA associated with deep-seated skin infections are spreading in Japanese communities, particularly in Ishigaki, Okinawa.

RESUMO

BACKGROUND: Although proximal gastrectomy (PG) is widely accepted as a function-preserving operation for early upper-third gastric cancer, postoperative disorders, such as reflux or gastric stasis, have often been pointed out. From the perspective of postoperative disorder, the choice of total gastrectomy (TG) or PG for such cancers is still controversial. By using the newly developed Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, the quality of life after TG and PG was compared. METHODS: The PGSAS-45 consists of 45 items composed of the SF-8 and GSRS scales and 22 new items. The main outcomes are measured by seven subscales (SS) covering symptoms, physical and mental component summary (SF-8), meals (amount and quality), ability to work, dissatisfaction for daily life, and change in body weight. A total of 2,368 eligible questionnaires were acquired from 52 institutions. From these, 393 patients with TG and 193 patients with PG were selected and compared. RESULTS: The PG was better than TG in terms of body weight loss (TG 13.8% vs. PG 10.9%; p = 0.003), necessity for additional meals (2.4 vs. 2.0; p < 0.001), diarrhea SS (2.3 vs. 2.0; p = 0.048), and dumping SS (2.3 vs. 2.0; p = 0.043). There were no differences in the other main outcome measures. CONCLUSIONS: Proximal gastrectomy appears to be valuable as a function-preserving procedure for early upper-third gastric cancer.

RESUMO

BACKGROUND: Lack of a suitable instrument to comprehensively assess symptoms, living status, and quality of life in postgastrectomy patients prompted the authors to develop postgastrectomy syndrome assessment scale (PGSAS)-45. METHODS: PGSAS-45 consists of 45 items in total: 8 items from SF-8, 15 items from GSRS, and an additional 22 items selected by 47 gastric surgeons. Using the PGSAS-45, a multi-institutional survey was conducted to determine the prevalence of postgastrectomy syndrome and its impact on everyday life among patients who underwent various types of gastrectomy. Eligible data were obtained from 2,368 patients operated and followed at 52 institutions in Japan. Of these, data from 1,777 patients were used in the current study in which symptom subscales of the PGSAS-45 were determined. We also considered the characteristics of the postgastrectomy syndrome and to what extent these symptoms influence patients' living status and quality of life (QOL). RESULTS: By factor analysis, 23 symptom-related items of PGSAS-45 were successfully clustered into seven symptom subscales that represent esophageal reflux, abdominal pain, meal-related distress, indigestion, diarrhea, constipation, and dumping. These seven symptom subscales and two other subscales measuring quality of ingestion and dissatisfaction for daily life, respectively, had good internal consistency in terms of Cronbach's α (0.65-0.88). CONCLUSION: PGSAS-45 provides a valid and reliable integrated index for evaluation of symptoms, living status, and QOL in gastrectomized patients.

RESUMO

BACKGROUND: Proximal gastrectomy with esophagogastrostomy (PGEG) has been widely applied as a comparatively simple method. In this study, we used a questionnaire survey to evaluate the influence of various surgical factors on post-operative quality of life (QOL) after PGEG. METHODS: In this post-gastrectomy syndrome assessment study, we analyzed QOL in 2,368 cases. Among these, 193 had undergone proximal gastrectomy and 115 had undergone PGEG. The Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 is a questionnaire consisting of 45 items, including the SF-8, the Gastrointestinal Symptom Rating Scale (GSRS), and other symptom items seemed to be specific to post-gastrectomy. The 23 symptom items were composed of seven symptom subscales (SS), including esophageal reflux, abdominal pain, and meal-related distress. These seven SS, total symptom score, ingested amount of food per meal, necessity for additional meals, quality of ingestion SS, ability to work, dissatisfaction with symptoms, dissatisfaction with the meal, dissatisfaction with working, dissatisfaction with daily life SS and change in body weight were evaluated as main outcome measures. In PGEG cases, we evaluated the influence on QOL of various surgical factors, such as procedures to prevent gastroesophageal regurgitation and size of the remnant stomach. RESULTS: The scores for esophageal reflux and dissatisfaction with the meal were higher in patients who had not undergone an anti-reflux procedure. In most cases, the preserved remnant stomach was more than two-thirds the size of the pre-operative stomach. When comparing patients with a remnant stomach two-thirds the pre-operative size and those with more than three-quarters, the diarrhea SS and necessity for additional meals scores were lower in the group with more than three-quarters. The indigestion, constipation, and abdominal pain subscales, and the total symptom score, were higher in patients who had not undergone pyloric bougie than in those who had. CONCLUSION: These results indicated that QOL was better in patients with a large remnant stomach. Procedures to prevent gastroesophageal reflux, and the use of pyloric bougie as a complementary drainage procedure, were considered effective ways to reduce the deterioration of QOL.

RESUMO

AIM: Hypertensive disorders of pregnancy (HDP) are among the obstetric complications reportedly associated with later-life cardiovascular disease (CVD). This study examined physicians' recognition of reproductive history by elucidating their attitude and knowledge. METHODS: This study included council members of the Japan Atherosclerosis Society. An Internet-based survey was conducted between August 9 and September 9, 2022. RESULTS: A total of 137 council members completed the questionnaire (response rate: 36%). In terms of the internal medicine subspeciality of the participants, endocrinology was the most common (46%), followed by cardiology (38%). About 70% of the participants considered reproductive history to be important and obtained more information than those who considered it otherwise. In the questionnaire for knowledge about HDP and future diseases, physicians correctly answered 6.8 of 9 questions. Endocrinologists were more likely to ask regarding reproductive history at the initial visit than cardiologists (82.5% vs. 61.5%; p=0.012) and obtained more information from women below 50 years old. Contrarily, cardiologists obtained information on reproductive history from older women (those approaching menopause and those in their 60s and 70s). CONCLUSION: We found that physicians had a high level of knowledge about HDP and the importance of reproductive information. However, the manner of obtaining information, including the target population, differed depending on the subspeciality. In the future, effective interventions for women with a history of HDP need to be developed in order to encourage physicians to obtain reproductive information to prevent CVD.

RESUMO

The glycosylphosphatidylinositol (GPI) attachment is a most important post-translational modification of proteins that plays essential roles in promoting the biochemical activities of eukaryotic cells. Described here is an analysis of the amino acid properties of mammalian GPI-anchored proteins (GPI-APs) and the development of an innovative method of detecting them. GPI-APs are characterized by two high-hydropathy regions: the signal peptide, located inside the Endoplasmic Reticulum (ER), and the GPI attachment signal, a sequence adjacent to the GPI-anchoring site (the ω-site). Especially in sequence analysis of known GPI-APs, there were some distinct aspects of the amino acid propensities around the ω-sites. Therefore, a method of detecting GPI-APs was developed based on hydropathy profiles and a position-specific scoring matrix (PSSM) calculated by position-specific amino acid propensities. First, sequences of GPI-APs and negative controls, determined by screening based on hydropathy and residue volume profiles, were aligned based on residue volume profiles in the C-terminal region, and the position-specific amino acid propensities of each group were calculated according to their alignment positions. Then, a PSSM was devised using the amino acid propensities of GPI-APs and negative controls, and discrimination scores were estimated for each dataset. Based on these scores at a threshold was fixed for each dataset. GPI-APs were detected with 81.1% sensitivity and a 0.818 success rate in an optimized calculation region determined by adjusting the window size of this region using a 5-fold dataset. The results indicate that a PSSM around the ω-site can effectively discriminate GPI-APs.

RESUMO

Ataxia-ocular apraxia 2 (AOA2) was recently identified as a new autosomal recessive ataxia. We have now identified causative mutations in 15 families, which allows us to clinically define this entity by onset between 10 and 22 years, cerebellar atrophy, axonal sensorimotor neuropathy, oculomotor apraxia and elevated alpha-fetoprotein (AFP). Ten of the fifteen mutations cause premature termination of a large DEAxQ-box helicase, the human ortholog of yeast Sen1p, involved in RNA maturation and termination.

RESUMO

Idiopathic pulmonary fibrosis (IPF) is a severe and progressive chronic fibrosing interstitial lung disease with causes that have remained unclear to date. Development of effective treatments will require elucidation of the detailed pathogenetic mechanisms of IPF at both the molecular and cellular levels. With a biomedical corpus that includes IPF-related entities and events, text-mining systems can efficiently extract such mechanism-related information from huge amounts of literature on the disease. A novel corpus consisting of 150 abstracts with 9297 entities intended for training a text-mining system was constructed to clarify IPF-related pathogenetic mechanisms. For this corpus, entity information was annotated, as were relation and event information. To construct IPF-related networks, we also conducted entity normalization with IDs assigned to entities. Thereby, we extracted the same entities, which are expressed differently. Moreover, IPF-related events have been defined in this corpus, in contrast to existing corpora. This corpus will be useful to extract IPF-related information from scientific texts. Because many entities and events are related to lung diseases, this freely available corpus can also be used to extract information related to other lung diseases such as lung cancer and interstitial pneumonia caused by COVID-19.

RESUMO

Aim: The current study compared the postoperative quality of life (QOL) between the esophagogastrostomy method (PGEG) and double tract method (PGDT) after proximal gastrectomy using the Postgastretomy Syndrome Assessment Scale (PGSAS)-45. Methods: Among the 2364 patients who received the PGSAS-45 questionnaire, 300 PGEG and 172 PGDT cases responded. The main outcomes measures (MOMs) consisted of seven subscales (SS) covering symptoms, meals (amount and quality), ability to work, dissatisfaction with daily life, physical and mental component summary of the 8-Item Short Form Health Survey (SF-8), and change in body weight, and were compared between PGEG and PGDT. Results: Overall, PGDT promoted significantly better constipation SS scores (p < 0.05), whereas PGEG tended to promote better body weight (BW) loss% (p < 0.10). A stratified analysis based on the remnant stomach size revealed that among those with a remnant stomach size of 1/2, PGDT had significantly better constipation and dumping SS scores (p < 0.05) and tended to have better working conditions (p < 0.10) compared to PGEG. Even among those with the remnant stomach size of 2/3, PGDT had significantly better diarrhea SS scores, lesser dissatisfaction with symptoms, and better dissatisfaction with daily life SS scores (p < 0.05) and tended to have better constipation SS scores and lesser dissatisfaction with work (p < 0.10) compared to PGEG. Conclusions: After comparing the QOLs of PGEG and PGDT, the stratified analysis according to remnant stomach sizes of 1/2 and 2/3 revealed that PGDT was relatively superior to PGEG for several MOMs.

RESUMO

IMPORTANCE: USA300 is an MRSA clone producing PVL, a toxin associated with SSTIs. ΨUSA300 is a USA300 variant recently identified in Japan by Takadama et al. (15). Here, we found that the prevalence rate of PVL-positive MRSA in S. aureus was elevated in the Japanese community, and ΨUSA300 accounted for most of them. ΨUSA300 strains have been isolated from several areas in Japan and were associated with deep-seated SSTIs. This study highlighted the emerging threat posed by ΨUSA300 in Japan.

RESUMO

BACKGROUND/AIMS: Gastric cancer is the most common cancer in Japan. Genome-wide gene expression in the jejunal pouch mucosa was examined using a DNA microarray and quantitative real-time PCR (qPCR) to evaluate the safety, especially with regard to carcinogenic changes, of the jejunal pouch in patients who showed long-term survival. METHODOLOGY: Biopsy samples of jejunal pouch and jejunal conduit were collected from four patients who had undergone gastrectomy 9 to 13 years previously. Total RNA was extracted, amplified to give complementary RNA, labeled with Cyanine 3-CTP and hybridized with a whole human genome oligo microarray (44k). Gene expression was confirmed partly by qPCR. RESULTS: Although some changes in the expression of 417 reported cancer genes were observed with the DNA microarray, crucial changes related to small intestinal adenocarcinoma were not observed. Changes in the expression of eight genes related to small intestinal adenocarcinoma were also not detected by qPCR. CONCLUSIONS: Crucial changes in the expression of genes related to small intestinal adenocarcinoma were not observed in the jejunal pouch of these four patients with gastric cancer by either DNA microarray or qPCR. The present results support the safety of the use of a jejunal pouch with a food pooling function in patients who show long-term survival after gastrectomy.

RESUMO

BACKGROUND: Although double tract reconstruction after proximal gastrectomy (PGDT) is commonly performed for proximal gastric or esophagogastric junction cancer, the impact of the procedure on postoperative quality of life (QOL) has not been clarified. We aimed to clarify the optimal PGDT procedure in terms of postoperative QOL. METHODS: Postoperative QOL was analyzed in 172 patients who underwent PGDT for proximal gastric cancer and were enrolled in the PGSAS-NEXT study, a multicenter cross-sectional study in Japan (UMIN000032221), in relation to the remnant stomach size, length of interposed jejunum between the esophagojejunostomy (E-J) and jejunogastrostomy (J-G), and size of the J-G. RESULTS: The remnant stomach size was approximately one-third in 13, half in 97, and two-thirds in 60 patients. Dissatisfaction scores for symptoms, diet, work, and daily life subscales were lower in patients with a larger stomach (p < 0.05). These patients also scored better in terms of weight loss (- 13.5%, - 14.0%, and - 11.2%, respectively) and amount of food ingested per meal (52%, 62%, and 66%). The length of the interposed jejunum was ≤ 10 cm in 62 and ≥ 11 cm in 97 patients. Weight loss (- 11.3% and - 13.8%) and dissatisfaction scores were better in the ≤ 10 cm group (p < 0.05). J-G size was ≤ 5 cm in 27 and ≥ 6 cm in 135 patients. The amount of food ingested (56%, 64%) and dissatisfaction scores were better in the > 6 cm group (p < 0.05). CONCLUSIONS: Larger remnant stomach, shorter length of interposed jejunum, and longer J-G might contribute to better postoperative QOL after PGDT.

RESUMO

BACKGROUND: Following a total gastrectomy, patients suffer the most severe form of postgastrectomy syndrome. This is a significant clinical problem as it reduces quality of life (QOL). Roux-en-Y reconstruction, which is regarded as the gold standard for post-total gastrectomy reconstruction, can be performed using various techniques. Although the technique used could affect postoperative QOL, there are no previous reports regarding the same. AIM: To investigate the effect of different techniques on postoperative QOL. The data was collected from the registry of the postgastrectomy syndrome assessment study (PGSAS). METHODS: In the present study, we analyzed 393 total gastrectomy patients from those enrolled in PGSAS. Patients were divided into groups depending on whether antecolic or retrocolic jejunal elevation was performed, whether the Roux limb was "40 cm", "shorter" (≤ 39 cm), or "longer" (≥ 41 cm), and whether the device used for esophageal and jejunal anastomosis was a circular or linear stapler. Subsequently, we comparatively investigated postoperative QOL of the patients. RESULTS: Reconstruction route: Esophageal reflux subscale (SS) occurred significantly less frequently in patients who underwent antecolic reconstruction. Roux limb length: "Shorter" Roux limb did not facilitate esophageal reflux SS and somewhat attenuated indigestion SS and abdominal pain SS. Anastomosis technique: In terms of esophagojejunostomy techniques, no differences were observed. CONCLUSION: The techniques used for total gastrectomy with Roux-en-Y reconstruction significantly affected postoperative symptoms. Our results suggest that elevating the Roux limb, which is not overly long, through an antecolic route may improve patients' QOL.

RESUMO

AIM: Total gastrectomy results in the complete loss of gastric function and the development of severe postgastrectomy syndrome. During the jejunal pouch procedure following total gastrectomies, a substitute stomach is created to alleviate the effects of postgastrectomy syndrome. However, the procedure's effectiveness remains controversial. This study aimed to explore the effect of jejunal pouch creation after total gastrectomy on postoperative quality of life. METHODS: A nationwide multi-institutional cross-sectional study, the Postgastrectomy Syndrome Assessment study NEXT, used the Postgastrectomy Syndrome Assessment Scale-45 questionnaire to explore the optimal gastrectomy procedure for cancer located in the upper third of the stomach or around the esophagogastric junction. The questionnaire consists of 45 items consolidated into 19 main outcome measures relating to postgastrectomy symptoms, amount of food ingested, quality of ingestion, ability for working, level of satisfaction for daily life, and the physical and mental component summary of the 8-Item Short Form Health Survey. Eligible completed questionnaires were retrieved from 1909 patients. Of these, the data were analyzed for 1020 patients who underwent total gastrectomy and 93 patients who underwent jejunal pouch creation after total gastrectomy. RESULTS: Postoperative quality of life was compared between patients with and without pouches. The analysis revealed that patients with pouches, particularly oral pouches, experienced substantially improved postoperative quality of life than those without, even after adjusting for several clinical factors using multiple regression analyses. CONCLUSION: The results suggest that total gastrectomy with jejunal pouch creation, particularly oral pouches, may significantly improve postoperative quality of life.
